Lenovo ThinkPad T420s MSRP $ “The LenovoT420s is an excellent laptop for business users, and also well worth the consideration of consumers who prefer an excellent keyboard and durable design to flashy aesthetics.” Pros Durable construction High-resolution display Excellent performance Reasonable price Cons Not particularly thin or light Lackluster battery life Display isn’t great for multimedia The ThinkPad T Series is an elder among laptops. IBM introduced the first laptop in the line, the T20, about 12 years ago. Since then the series has been consistently updated and has never once been removed from the market. Only the ThinkPad X Series has enjoyed a similar tenure. IBM’s original T20 was offered only with a display, but over the years the line has expanded. High performance and variants were made available. More recently, Lenovo decided to spin off a thinner, lighter version — resulting in the T420s. Though this is the thin-and-light version of the T420, don’t mistake it for an Ultrabook. The display and maximum thickness of just over one inch seemed modern when the original T400s arrived in 2009, but today it’s merely average. It does allow for a standard Core i5-2520M processor, however, which means performance should be much better than what is provided by today’s thinnest laptops. Lenovo is debuting an Ultrabook version of the T-Series, called the T430u, later this year. Which raises the question Is the T420s a good choice, or is this thin and light losing ground to more modern designs? Let’s find out. Video overview Still in black When Lenovo took over the ThinkPad line from IBM there was widespread fear that the brand would be watered down. Instead, the company has remained shockingly stubborn. This T420s is thin, but its appearance is otherwise not much different than the laptops made ten years ago. From an aesthetic standpoint the use of matte black is a terrible choice, but that’s not the point. Functionality is the focus here. The expanses of non-gloss material ensure that fingerprints are rarely an issue. Dings and scratches also tend to be obscured. While a shiny new consumer laptop may look worse for wear a few years down the road, this laptop will display its scars with pride. The T420s’ designation as a thinner version of the T420 is literal. We’ve had the chance to see both, and the design elements are the same right down to the size of the display bezel, the hinges used and the location of the latch yes, this laptop has a display latch, a feature long gone from consumer products. Connectivity is the only major change. Due to its thinner profile this laptop offers only three USB ports, DisplayPort, VGA, Ethernet and a card reader. That’s down a couple ports to the normal T420, but it’s also much better than what is provided by most laptops of similar size. Better still, the ports are mostly along the rear of the laptop. That’s beneficial because it means peripheral cords are less likely to get in your way. Old-school keyboard Similarities between the T420 and T420s continue with the user interface. The keyboards on both appear to be identical, which means that the thinner model has the same excellent key feel. While most of the competitions — including HP’s own business-oriented Elitebooks — have transitioned over to island-style keyboards, Lenovo has continued on with beveled keys. The result is not as visually attractive, but we think this design is better for high-speed touch typing. Users new to the ThinkPad brand will undoubtedly be tripped up by the location of the function key, which is located where the Ctrl key is on every other keyboard ever produced. This strange layout has been used for years, so it’s unlikely to be changed soon. On the other hand, the T420s offers dedicated buttons for speaker mute, microphone mute and volume as well as double-sized Escape and Delete keys. These enhancements more than make up for the layout’s other oddities. The touchpad is extremely small for a laptop of this size. It’s obvious that you’re expected to use the trackpointer a little red pointing stick in the middle of the keyboard instead. Users who’ve never tackled a trackpointer before are bound to be confused by it, but there are benefits. Once you’ve become accustomed to it you can navigate via mouse without lifting your hands from the keyboard. Great for business, OK for entertainment The T420s is a business laptop, and as such it comes with a matte display, making it possible to use the laptop in many different environments. Even outdoors use is possible with the display’s brightness turned to maximum. Usually the downside to a matte display is less-than-stellar performance in movies and games, and that’s certainly the case here. You don’t get the “pop” of vibrant colors that you receive from a decent glossy laptop display. Performance in movies and games is still adequate, however — and better than matte displays we’ve seen in the past. Part of the reason for this may be the resolution of 1600x 900, which is high for a display. Audio quality has never been a focus of the ThinkPad brand, but the sound the 420s emits is surprisingly adequate. It has all the typical laptop issues with bass and distortion, but maximum volume is sufficiently loud and clear. Cool and quiet At idle, the fan of the T420s isn’t audible. At load, the fan spins up a bit, but still remains quiet. This is one of the least audible cooling systems that we’ve ever heard. You’d think that the low fan speed would result in warm operation, but that’s not the case. At idle most of the laptop’s surfaces are between 70 degrees and 80 degrees Fahrenheit, which is just barely above room temperature. Placing the laptop under load with a stress test did raise temperatures, but almost all surfaces remained under 90 degrees. The only potential source of discomfort is the left rear bottom of the laptop, which is where the exhaust is located. Temperatures here reached 103 degrees, which means that lap use could be uncomfortable if the processor is heavily stressed. That battery goes where? Though built to be thin and light, the T420s isn’t the most portable laptop around. Its 14-inch display puts it at a disadvantage compared to or laptop. The laptop’s weight of about pounds is far from classleading, as well. With that said, the T420s is reasonably small. It will fit in most bags that accommodate a laptop and is light enough to tote around on a regular basis. All ThinkPad T420s laptops come with a standard six-cell battery. In our Battery Eater’s Standard Test it lasted just one hour and nine minutes, but in the Reader’s Test is lasted a reasonable five hours and thirty two minutes. Typical mobile use will result in between four and five hours of endurance. That’s not bad, but it’s not great, either. If you need more life you can buy a three-cell bay battery for $120. This battery replaces the optical drive, which slides out using a fool-proof latch system. With the extended life battery installed, life in the Battery Eater Standard Test goes up to two hours and ten minutes and the Reader’s Test is extended to an impressive eight hours and thirty nine minutes. There’s an optional nine-cell battery for people who need even more life, but it was not provided with our review unit. Software As with other ThinkPads, our T420s came with Lenovo’s bundled ThinkVantage software. It includes a wide variety of software such as ThinkVantage Connections, which is a replacement to the standard Windows wireless manager. Unlike most such bundled solutions, the software offered by Lenovo is actually better than the standard Windows solution. This is also true for the Power Manager. Not everything about the included software is great, however. Lenovo includes advertisements for other ThinkVantage services in portions of the bundled software interface by default, which is annoying. In addition, the Virus Protection section recommends Norton Internet Security. It’d be more useful to recommend Microsoft’s free Security Essentials software. Strong performance Though thin, the T420s is not so thin that it prevents the use of normal Core i5 processors. That’s a major advantage older and thicker ultraportables have over newer Ultrabooks, and its shows in the performance numbers. SiSoft Sandra’s Processor Arithmetic test achieved a combined score of which sets a new record among the laptops we’ve reviewed. The 7-Zip score of 8,247 MIPS is also the highest we’ve yet recorded. Considering the strong processor performance, the score of 2,358 returned by PCMark 7 seems low. The reason for this, as mentioned in other reviews, is that PCMark 7 heavily favors solid state drives. If we take laptops equipped with SSDs out of the running the score of 2,358 is strong. Only the HP Envy 15 scored higher. Nvidia NVS 4200M discrete graphics can be had as an option, but our review unit did not come equipped with it. Instead it relies on Intel’s HD 3000, which can’t run 3DMark 11. 3DMark 06 returned a score of 3,701, which is a bit low for a laptop of this configuration. Combine this with a 1600 x 900 display and you have recipe for terrible gaming performance. Even older 3D games will need to be played with many detail options turned off. No one has ever mistaken a ThinkPad for a gaming laptop, however, so the lack of 3D gaming prowess isn’t a problem. Overall performance from the T420s is extremely strong, held back only by the mechanical hard drive. Solid state drives are available as an option. We highly recommend them if you’re interested in maximum performance. Conclusion The ThinkPad T420s is another example of Lenovo’s stubbornness. Besides the hardware, which is quick, there’s nothing about this laptop that is particularly modern. The entire design philosophy, from the boring matte black surfaces to the beveled key caps, could easily be at home on a laptop built five years ago. But being stubborn isn’t bad when you have it right. This is a laptop built for people who use their laptops for work every day, and for that use the T420s is perfect. It’s simply a miniaturized version of the T420, offering the same performance in a more portable package. While the T420 might be used around an office, the T420s can be taken nearly anywhere. You might expect to pay a higher price for the slimmer chassis, but that doesn’t seem to be the case. Right now our review unit can be yours for just $999, while a similar T420 is $949. That’s not much of a difference. The only weakness of the T420s is battery life. It’s not terrible, but it’s a little below average for a modern ultraportable. The included three-cell extended battery does extend life, but it requires the removal of the optical drive and is an additional cost. It’d be nice if this laptop managed six or seven hours in real-world use without additional juice. One minor disadvantage can’t spoil this party, however. The T420s is an excellent laptop for business users, and also well worth the consideration of consumers who prefer an excellent keyboard and durable design to flashy aesthetics.

Insidethe Lenovo ThinkPad 420s is plenty of power, which makes this a business laptop suited to people who need real grunt for demanding applications. The Intel Core i7 2640M is clocked at a Uma constante invariável. O design experimentado e testado do Thinkpad praticamente se manteve intacto no exterior. Mas a partir de agora, o novo hardware Sandy Bridge faz seu trabalho dentro do T420. Além disso, o compacto portátil de escritório ostenta uma excelente configuração de comunicações para o campo Lenovo sem dúvida criou um nome por si mesma no campo empresarial com os portáteis Thinkpad. A série T deseja "oferecer os melhores serviços de segurança, comodidade, serviços e suporte" se acordo com o web site da Lenovo, e, portanto, distingue-se do topo da série W significantemente mais forte. Em compensação, a série X pontua com uma mobilidade mais ampla. O nosso equipamento de teste é o de 14 polegadas da série T, chamado T420. Adjacentemente, o modelo de 15 polegadas, T520, também é oferecido e está em análise ao mesmo tempo. Essencialmente os portáteis Tx20 somente se diferenciam dos modelos anteriores, chamados T410 e T510, por uma atualização no hardware para os novos processadores Sandy Bridge. O nome completo do equipamento é T420 4236-NGG. Dentro dele um CPU Intel Core i7 2620M faz o seu trabalho. O chip gráfico incorporado, Intel HD Graphics 3000, esta exclusivamente disponível para a saída de vídeo em nosso modelo de teste. Esta configuração é suportada por uma memória de quatro gigabytes DDR3 e um veloz disco rígido de 500 GB com uma velocidade de rotação de 7200 rpm. Além de vários processadores Core i, o T420 também está disponível com uma placa de vídeo dedicada NVIDIA NVS 4200M e tecnologia Optimus – pelo menos nos EUA. Conseqüentemente, a valoração das partes contingentes do desempenho depende da configuração real e pode não necessariamente ser aplicado a outros modelos. O Thinkpad T420 pode ser praticamente visto como um oponente imediato do Latitude E6420 basicamente configurável se forma similar. Enquanto a Dell optou por um design completamente novo, a Lenovo contrariamente continua com o design experimentado e testado para o Thinkpad T420. Vamos demonstrar até que grau se diferenciam ambos os portáteis ou 15 polegadas, o visual foi mantidoA primeira vista, o T420 não parece de diferenciar muito do T410. Mas isto é enganoso. Por uma coisa, a diagonal da tela se reduziu de 14,1 polegadas para 14 polegadas. O mesmo se aplica para a altura e largura do portátil, sendo que a profundidade interessantemente aumentou um pouco. As medições para comparação 30,5x340,5x233mm para o T420 e 32x336x239 para o T410. Embora muitas poucas mudanças tenham sido feitas na conectividade, a Lenovo permanece com o design leve de concha. Nenhuma modificação pode ser encontrada nas opções de cores ou materiais. O case quase completamente preto foi feito de plástico. A sensação táctil corresponde à seleção dos materiais. No entanto, as superfícies mate e levemente ásperas nãos são desagradáveis. A estabilidade do case é basicamente satisfatória. Mas ainda mostra as mesmas deficiências conhecidas do T400. Portanto, na área do compartimento Ultra Bay e na coberta plástica sobre o teclado. O case pode ceder um pouco e ranger sob pressão seletiva. Os componentes da tela resistem bem os nossos testes de rigidez e pressão. Quando o portátil é levantado pelas bordas não se deforma quase nada. As dobradiças primeiro cedem antes que surjam distorções na imagem sob pressão seletiva. Em compensação, o marco da tela cede evidentemente quando é aplicada pressão e permite que os desvios da imagem se tornem visíveis. Gostamos das dobradiças metálicas que dificilmente se balançam depois de ajustar o ângulo de apertura. Surpreendentemente, elas não suportam muito bem as condições de trabalho turbulentas viagem em trem. Como são suaves e a unidade base é suficientemente pesada, é possível abrir e fechar o portátil com uma mão. O ângulo máximo de apertura de um pouco mais de 100 graus não causa restrição alguma. Adicionalmente ao design de concha, o gancho ramshorn contribui para o transporte seguro. Ele mantém o equipamento seguramente fechado e pode ser aberto facilmente com o botão deslizante na frente. Vamos começar com um tour ao redor do próprio equipamento. Notamos que o posicionamento favorece um pouco aos usuários destros. Dependendo da utilização de entradas individuais, alguns cabos podem encher o lado esquerdo, o qual poderia obstruir consideravelmente a área de trabalho à esquerda do portátil. Duas das cinco entradas USB o entrada para tela, a VGA e a RJ45 estão na área central esquerda. Em oposição, a Lenovo tomou cuidado no posicionamento de entradas que potencialmente estarão ocupadas de forma permanente, como as outras duas entradas USB e a entrada combinada eSATA/USB, na área posterior direita. Adicionalmente, a direita aloja, da frente para trás, um conector de áudio combinado de 3,5mm, o drive ótico em um compartimento Ultra Bay, um leitor de cartões 4em1 que suporta SD, MM, SDHC, SDXC, e uma entrada ExpressCard34 port. A parte posterior é completada por uma entrada USB energizada e um modem RJ11. O adaptador de força também é conectado na parte posterior do case. Infelizmente, a Lenovo, como a Dell no seu E6420, esqueceu-se de instalar uma entrada USB no curso de atualização. Embora a interface eSATA também ofereça um índice de transferência de dados mais alto que o de um USB cada vez mais memórias de armazenamento mássico estão sendo oferecidas com entradas USB e o eSATA esta desaparecendo pouco a pouco do mercado. Em comparação com a concorrência, também notamos que a Dell recorre à utilização de uma entrada HDMI no E6420 e por isso aceita as restrições pertinentes. Em oposição, a Lenovo permanece decidida na instalação de uma entrada para tela diretamente no equipamento. Comparado com o seu predecessor, o T410, quase nada significante foi modificado. Apenas uma interface USB energizada foi adicionada. Além disso, a disposição das interfaces foi corrigida, mas não realmente melhorada. Portanto, se você encontrar cabos na área de trabalho do lado do portátil, ou se você não deseja voltar a conectar todos os cabos após o uso móvel, você pode fazer uso de uma estação docking. A entrada docking está, como é habitual, na parte inferior do portátil. Por falar em estações docking – continua sendo interessante ver quais soluções docking conseguirão chegar a te a Europa. Atualmente, dois modelo estão disponíveis para oT420 nos EUA O ThinkPad Mini Dock Plus Series 3 US/Canada/LA -> infromação do fabricante por cerca de 250 Dólares Americanos. Ele permite conectar três monitores externos adicionais adicionalmente à tela instalada. Em segundo lugar, a entrada ThinkPad Port Replicator Series 3 -> informação do fabricante por cerca de 280 Frontal Botão deslizante para abrir Lado Esquedo Ventilador, VGA, RJ45 LAN, dois USB compartimento para disco rígido Lado Posterior RJ11, USB energizado, bateria, conector de força, ventilador Lado Direito conector de áudio combinado, drive ótico, ExpressCard34, Leitor de Cartões 4em1, USB entrada combinada USB/eSATA, compartimento de segurança KensingtonComunicação Como o T410, o nosso T420 de teste ganha pontos uma extensa configuração de comunicação. Tudo o que é útil e está disponível está instalado. Um módulo Bluetooth versão é opcional, e está instalado no nosso equipamento de teste. Este permite a troca de dados com equipamentos pequenos portáveis, como PDAs ou telefones celulares. Também opcional é um módulo de banda larga móvel F5521gw Mobile Broadband também instalado em nosso Thinkpad. O compartimento SIM equivalente está localizado no compartimento da bateria. Os cabos da antena estão instalados para que assim um módulo UMTS/HSPA possa ser instalado depois. Com respeito ao WLAN, são dadas várias opções. Um módulo Centrino Ultimate-N 6300 AGN agn da Intel está no equipamento de teste. O portátil pode ser conectado às redes Ethernet através da conexão de rede Intel 82579 LM Gigabyte. As videoconferências não são um problema com a câmera opcional de 720p HD es esta configuração. Segurança Adicionalmente ao obrigatório Seguro Kensington Lock, o T420 também tem um leitor de impressões digitais, entre outras coisas. Um teclado a prova de derrames evita a perda de dados no caso de um acidente com líquidos. Suprimentos Além da parafernália necessária, como o adaptador de força e bateria, apenas um pouco de informação impressa está incluída no conteúdo da entrega. O usuário deve criar DVDs de recuperação para o pré-instalado Windows Professional 64bit imediatamente depois da compra. Porém, isto não é um problema com a conveniente ferramenta ThinkVantage. Garantia A garantia padrão para a gama T é de três anos na Europa. A garantia básica inclui apenas um ano de serviço “bring-in” nos EUA. Várias extensões da garantia podem ser adquiridas Nem o design nem a disposição foram modificadas em comparação com o T410. Aparte das teclas STRG e FN trocadas, estamos lidando com uma disposição padrão com agrupações de teclas claramente posicionadas. A tecla blue ThinkVantage mais uma vez é a tecla adicional mais chamativa. Ela abre as ferramentas ThinkVantage, respectivamente um processo de recuperação pode ser iniciado durante o booting. À esquerda dela está um botão de mute para os alto falantes e microfone e um controle giratório para o volume. A iluminação do teclado está integrada no marco superior da tela, como estava no T410. Esta pode ser ligada /desligada com as teclas FN+PGUP. A luz pode ajudá-lo a encontras o seu caminho nos dispositivos de entrada na escuridão, mas em nossa opinião não se compara com teclado com iluminação posterior. Os digitadores produtivos irão achar o teclado do Thinkpad muito agradável devido a suas qualidades mecânicas, deslocamento bem dosado da tecla e claro ponto de pressão. Adicionalmente, as teclas côncavas aumentam o conforto da digitação. Infelizmente, o teclado torna-se muito barulhento especialmente durante a digitação enérgica. No entanto, a digitação não é um problema desde o início. Touchpad e Trackpoint As semelhanças com o T410 são impressionantes aqui. O touchpad e trackpoint podem ser independentemente desabilitados e habilitados através do F8+FN. O touchpad comprova ter uma agradável superfície áspera com boas propriedades de deslizamento. O controle do cursor do mouse novamente é preciso sem problemas e os recursos multi-touch respondem conforme o esperado. Além disso, o rolamento através dos campos de rolamento na borda do touchpad também é possível. As bordas do touchpad dificilmente podem ser distinguidas do case que o rodeia devido a uma junta simples. Os botões correspondentes precisam de um pouco de tempo de adaptação, pois estão na borda angular. Eles são lisos, respondem bem sobre toda sua superfície e o clique não é muito barulhento. Alternativamente, também há um trackpoint vermelho. Ele permite uma navegação precisa do cursor do mouse. Os botões correspondentes são suficientemente silenciosos. Também não há reclamos com respeito à lugar do formato 1610 como é no T410, agora é usado um formato 169. A diagonal da tela foi marginalmente reduzida de 14,1 para 14 polegadas. Em compensação, a resolução foi aumentada de 1440x900 pixels para 1600x900 pixels. Com isso, agora há tantos pixels na altura total como no modelo anterior. No entanto, O dispositivo de teste ganhou um pouco de largura. Como é de se esperar de um equipamento empresarial, a superfície da tela foi revestida com um filme anti-reflexos. Com isso o equipamento não apenas atende os requerimento de telas de estações de trabalho, mas também é mais adequado para o trabalho em T420 tem melhorado no geral em comparação com o T410 em termos de avaliações. É mais brilhante e iluminado mais uniformemente. Apenas o valor de escuridão é levemente mais baixo que o do modelo anterior. Apesar de tudo, o melhor brilho resulta em um contraste um pouco mais alto. Em contraste, o E6420 pontua com um brilho máximo significantemente mais alto de 320 cd/m2 e ainda 277,7 cd/m2 em média. Em compensação, o portátil da Dell deve admitir a clara derrota no campo do valor de escuridão e contraste. 197cd/m²190cd/m²214cd/m²213cd/m²223cd/m²221cd/m²210cd/m²198cd/m²194cd/m² Distribuição do brilhoLEN40A1Gossen Mavo-MonitorMáximo 223 cd/m² Nits Médio cd/m²iluminação 85 %Contraste 1621 Preto cd/m² AdobeRGB 1998 Argyll 3D61% sRGB Argyll 3D Display P3 Argyll 3DComo pode ver nas fotos de comparação, que foram feitas com vários perfis de cores ICC, o T420 não foi feito para a edição profissional de imagens. O Adobe RGB e sRGB não são cobertos. Por isso está na mesma liga do Dell E6420 com o mesmo tamanho da tela e resolução. As diferenças em vista da reprodução de cores se tornaram visíveis em comparação com telas com qualidade especialmente alta. Elas podem ser encontradas, por exemplo, no Apple MacBook Pro 13 ou no Dell XPS 15. Inclusive o irmão mais velho do T420, o T520, ganha mais pontos aqui. Com uma superfície anti-refletiva e um brilho médio de mais de 200 cd/m2, que também está disponível no modo de bateria, o modelo de teste é muito adequado para o uso em exteriores. O conteúdo da tela permanece suficientemente legível inclusive sob a luz direta do ultimo ponto que vimos para avaliar a tela é a sua estabilidade dos ângulos de visão. Resulta satisfatório horizontalmente e a imagem pode ser reconhecida se problemas inclusive em ângulos muito estreitos. Como é habitual na maioria dos portáteis, os ângulos de visão no plano vertical são consideravelmente menores no T420. Conseqüentemente, você pode ter certeza que precisará ajustar o ângulo de visão freqüentemente para garantir uma imagem legível, especialmente durante o uso em exteriores. Quando muita gente esteja olhando para a tela ao mesmo tempo, seus olhos devem estar quase na mesma de Visão Lenovo Thinkpad T420 4236-NGGA série Thinkpad T420 de portáteis baseiam-se no chipset QM57 Express. Atualmente vários modelos com Core i5 ou i7 da segunda geração estão sendo oferecidos. Para ser exato, o nosso modelo de teste foi equipado com um CPU Intel Core i7 2620M Sandy Bridge. Atualmente é o processador dual core mais veloz da família Sandy Bridge que foi introduzido no início de 2011. Pode processar até quatro threads ao mesmo tempo graças ao Hyper Threading. A tecnologia Turbo Boost permite que os de um núcleo possam acelerar dinamicamente de 2,7 GHz até 3,4 GHz, dependendo da carga e capacidade de esfriamento. Em comparação com os processadores Arrandale, a função turbo foi melhorada entre outras do Sistema Lenovo Thinkpad T420 4236-NGG O chip Intel HD Graphics 3000 com suporte para DirectX 10 incorporado diretamente no processador está disponível para a saída de vídeo no nosso equipamento de teste. Por isso, o desempenho gráfico está quase no mesmo nível de uma placa Nvidia Geforce 310M de gama baixa. Como o Latitude E6420, modelos com uma NVIDIA NVS 4200M e Tecnologia Optimus estão listados nos EUA. Nosso T420 tem uma RAM de quatro gigabytes DDR3 disponíveis para a memória principal. Eles estão em um só chip, inacessível para o usuário. Apenas o segundo, ainda desocupado compartimento é acessível através da coberta de manutenção. O usuário pode fazer uma atualização facilmente. Devido ao sistema operacional Windows 7 Professional de 64bit, os quatro gigabytes da memória principal podem ser aproveitados eficientemente, ao contrário de uma versão de 32 bit, e não há nada que impeça uma atualização da RAM. O controlador de memória do processador pode controlar um máximo de até oito gigabytes de RAM DDR3-1066/ de Experiência Windows 7ProcessadorCálculos por RAMOperações de memória por da Área de Trabalho para Windows de jogosGráficos 3D empresariais e de rígido principalVelocidade de transferência de dados de R10 Rendering Single CPUs 64Bit5438 Points Cinebench R10 Rendering Multiple CPUs 64Bit11507 Points Cinebench R10 Shading 64Bit5566 Points Ajuda PCMark Vantage Result 7845 pontosAjuda Tanto o processamento como o desempenho de aplicativos é previsivelmente um pouco mais alto que o do E6420 equipado com um Core i3-2310M. Os índices de desempenho estão de acordo com as expectativas nesta configuração de hardware. O nosso candidato de teste atingiu uma pontuação total de 7845 pontos, o qual deve-se especialmente à sua alta sub-pontuação de comunicações, no teste PCMark Vantage para avaliar o desempenho geral. Por isso, esta inclusive no mesmo nível de máquinas para jogos mais potentes, como oAsus G73SW GeForce GTX 460M, Intel Core i7 2630QM, em termos de desempenho de do Desempenho Gráfico O equipamento de teste ainda pode se enfrentar com máquinas para jogos como o Asus G73SW em termos de desempenho de aplicativos. No entanto, em vista do hardware gráfico, não tem chance alguma no desempenho 3D como esperávamos desde o início. Isso é confirmado pelos resultados no Teste Cinebench Shading e os vários benchmarks 3DMark. Infelizmente, os resultados do teste estão por embaixo de aqueles que seriam os esperados para uma HD Graphics 3000. No entanto, como as medições de energia sempre se mantêm por abaixo do par, temos que lidar com um equipamento defeituoso. Outro indicativo disto é que a detecção de dispositivos da Ferramenta ThinkVantage falha regularmente. Para excluir um problema nas configurações verificamos o BIOS e as configurações de energia no Windows 7. Vamos tentar conseguir um equipamento de substituição para uma análise de atualização. Vamos consultar os nossos testes detalhados do chip Intel HD Graphics 3000 e da folha de especificações da HD Graphics 3000 para mais informação. 3DMark 05 Standard 6131 pontos3DMark 06 Standard Score 3381 pontos3DMark Vantage P Result 1696 pontosAjuda Velocidade de Transferência Mínima MB/s Velocidade de Transferência Máxima 102 MB/s Velocidade de Transferência Média MB/s Índice de Explosão MB/s O disco rígido do nosso equipamento de teste é um ST9500420AS da Seagate. Ele tem uma capacidade bruta de 500 GBs, onde uma parte é usada como uma partição de recuperação oculta.

Um gravador de DVD também está disponível como outro equipamento de armazenamento massivo. Para ser precisos, é um Optiarc DVD RW do Sistema O T420 sempre permanece suficientemente silencioso sem importar a carga. O ruído do sistema e de constantes 32,2 dBA com carga leve. O disco rígido é um pouco mais barulhento com 32,5 dBA durante o acesso. O portátil de teste atinge apenas um nível de ruído máximo de 35,2 dBA durante o nosso teste de estresse GPU e CPU com carga total. Por isso o ruído operacional sempre mantém um nível aceitável. No entanto, as avaliações do consumo de energia 28W máx. indicam que o processador não aproveita sua máxima capacidade possível mesmo durante o teste de estresse. Monitorando a freqüência do processador com a ferramenta CPUZ registramos a freqüência predefinida de 2,7 GHz para o CPU no teste de estresse. Isto significa que não há overclocking em nenhum dos núcleos e no GPU durante a carga. O CPU funciona com uma freqüência de 3,19 GHz quando apenas o Prime95 está ativado. Quando o Furmark é adicionado, o sistema reduz para 2,7 GHz. Também conseguimos registrar um máximo de 3,19 GHz no Cinebench R10 Single Core rendering. O medidor de freqüência permanece no mesmo nível no multi core rendering. Conseqüentemente a freqüência máxima possível do i7-2620M de 3,4 GHz não é aproveitada em nenhum estado testado. Apesar de tudo, os resultados de benchmark que são determinados no Cinebench R10 se mantêm dentro da faixa esperada dos CPUs i7-2620M e não demonstram irregularidades com respeito a possíveis afogamentos.

Alto falantes A qualidade dos alto falantes não pretende ser valorada como alta em um portátil de escritório para uso profissional como em, por exemplo, um portátil multimídia notebook. De fato, ambos os alto falantes estéreo, à esquerda e direita do teclado, são basicamente adequados para a voz. Não é possível desfrutar da música devido ao com diminuto, pobre em baixos e pesado nos agudos. Fones de alta qualidade, conectados ao conector combinado de áudio de 3,5 mm, podem remediar isto. O sinal é transmitido claramente, sem distorções e sem estática no teste apenas teste de áudio, sem medições.O nosso modelo de teste está no começo com uma bateria de lítio íon de 6 células de 57 Wh neste teste. Uma possibilidade de estender a duração da bateria é fazer o pedido da bateria de 9 células. A outra é o acoplamento de uma bateria de 9 células. De acordo com as especificações do fabricante, é possível uma duração máxima total da bateria de até 30 horas. Em qualquer caso, uma máxima duração de bateria de "apenas" sete horas e meia é possível com a matéria que temos em mãos. O teste BatteryEater's Reader determinou esta duração com brilho mínimo, com o módulo wireless desabilitado e em modo de economia de energia. Este índice é pouco realista para o uso prático devido ao mínimo é inútil brilho mínimo. Nós executamos o teste WLAN som um brilho utilizável, ou seja, desde o nível 12 a 15. Podemos fazer pesquisas na internet para até seis horas, também em perfis de economia de energia, neste cenário de baixa carga sem vídeos flash. A reprodução de um filme acaba depois de um pouco mais de três horas no teste de DVD. Foi executado com brilho máximo e módulos wireless desabilitados, bem como em modo "Vídeo". A duração da bateria cai em picada com aplicativos intensos 3D, brilho máximo, módulos wireless habilitados e modo de desempenho máximo. O teste BatteryEater Classic simula um cálculo OpenGL e registra uma mínima duração de bateria de apenas cerca de uma de Execução da Bateria Ocioso sem WLAN, min brilho 7h 28min Navegar com WLAN 5h 59min Carga máximo brilho 1h 06min O Latitude E6420 claramente tem a liderança nos testes de bateria devido a sua maior bateria de 9 células. As durações de bateria do nosso equipamento são, apesar de tudo, extraordinárias em relação com a capacidade da bateria. Isso se deve especialmente devido ao baixo consumo de energia. É um pouco mais baixo que o do E6420 com 6,8 para 11,5 watts no modo inativo. Surpreendentemente, o máximo consumo de energia não foi tão alto quanto esperávamos no teste de estresse 100% de carga do CPU e GPU. Somente o CPU comprova ter uma perda máxima de energia de 35 watts. No entanto, nossos medidores apenas registraram 28,6 watts para o sistema inteiro. Por isso, verificamos as configurações no PowerManagement da Lenovo em Windows 7 e as configurações do BIOS. Mas não encontramos nada em lugar algum. As configurações para o funcionamento conectado na tomada estão estabelecidas claramente em "Desempenho Máximo" no BIOS. O T420 também está disponível com uma placa de vídeo NVIDIA NVS 4200M dedicada nos EUA. Por isso a Tecnologia Optimus é usada para manter baixo o consumo de energia durante a carga baixa. Como o nosso equipamento de teste E6420 está equipado com a placa de vídeo NVIDIA NVS 4200M e opção Optimus, nosso T420 tem uma evidente vantagem no consumo de energia durante cenários de Thinkpad T420Além do aumento do desempenho esperado devido à nova geração de processadores, muitas coisas experimentadas e testadas foram mantidas. Isto também aplica-se tanto para o case como para as convenientes ferramentas pré-instaladas ThinkVantage. Pequenas modificações e upgrades podem ser encontrados na conectividade. Apesar de tudo, o usuário ainda tem que viver sem o USB Em compensação, uma entrada eSATA/USB foi instalada. A configuração de comunicações do portátil de teste é extensa. Todas as opções disponíveis são aproveitadas módulo de banda larga, Bluetooth versão WLAN com suporte para padrão n e gigabit Ethernet. Gostamos da tela de 14 polegadas que é marginalmente menor que a do T410 diagonal da tela. A disposição do desktop foi mantida, respectivamente inclusive foi melhorada em largura devido a uma resolução de 1600x900. Não há nada que impeça o uso móvel com a tela mate e o bom brilho. No entanto, o T420 apenas oferece valores padrão em termos de reprodução de cores. De acordo com o fabricante, supostamente é possível atingir uma duração de bateria de até 30 horas com a bateria de 9 células do sistema e adicionalmente, com a bateria acoplada de 9 células. Atingimos uma duração de bateria plausível de até 6 horas com nossa bateria de 6 células com uma capacidade de 57 Wh Teste WLAN. O T420 basicamente foi criado para clientes empresários que procuram por um sólido portátil de escritório com um bom desempenho de aplicativos e, apesar de tudo, boas qualidades móveis. Um leve aumento do desempenho em aplicativos 3D pode ser esperado nas configurações com uma placa de vídeo Nvidia NVS 4200M dedicada, que também suporta DirectX 11, listados nos EUA. No entanto, o nosso portátil de teste não sofrerá uma mutação para uma estação de trabalho co gráficos mais potentes mesmo com esta solução gráfica. Por cortesia da...

Find out more about how we test. Lenovo's ThinkPad T series notebooks have long been the gold standard for mainstream business systems because of their strong performance, superior build quality, and best-in-class keyboards. With the 14-inch ThinkPad T420, Lenovo has made a couple of changes, switching the screen to the now-standard 169 aspect ratio and giving it the latest Intel 2nd Generation Core series CPU. Is the T420, $1,179 as configured, the business notebook to beat?Update Read our review of the ThinkPad T460, the latest version of this computer. DesignThe ThinkPad T420 follows the classic ThinkPad aesthetic business users have come to know and love over the years. The matte black, rubberized lid with its simple silver logo and raven black sides, bottom, and interior are all long-time ThinkPad staples, as is the tiny red TrackPoint pointing stick that sits between the G and H keys. Like previous ThinkPad T Series notebooks, the T420 is designed for durability. The rubberized ABS plastic lid, carbon-reinforced bottom, and internal roll cage help protect against shocks and x 10 x 1 inches and pounds with the high-capacity nine-cell battery, the ThinkPad T420 is a bit larger and heavier than the Toshiba Tecra R840 x x inches, pounds, but it's still lighter than the HP Elitebook 8460p 13 x x inches, pounds and the Dell Latitude E6420 x x inches, pounds with its extended battery. Using the standard six-cell battery cuts the T420's length to 9 inches and its weight to pounds. Lenovo's ThinkPad T420s, designed as a lighter alternative, weighs only 4 pounds and measures only x x inches.[Which ThinkPad is Right for You?]Keyboard, Pointing Stick, TouchPadThe classic, spill-resistant keyboard on the ThinkPad T420 features 7 rows with a full range of keys, even rarely used ones such as scroll lock and pause. Enlarged Esc and Delete keys make it easy to perform these frequent functions. The combination of strong tactile feedback and a smile-shaped key surface allowed us to achieve an 86 word-per-minute score with a 1-percent error rate on the Ten Thumbs Typing Tutor test, well above our 80 wpm average. However, the typing experience on the 13-inch ThinkPad X1 remains the industry's best because of that notebook's soft-touch palm rest and even more responsive other ThinkPads, the T420 has both a TrackPoint pointing stick and a touchpad. We're huge fans of the TrackPoint because it provides the most accurate way to navigate around the desktop short of using a mouse, and it allows you to move the pointer without lifting your fingers off of the home row. If you don't like pointing sticks, the 3 x textured touchpad provides accurate navigation around the desktop, and its two discrete mouse buttons provide just the right amount of feedback. However, multitouch gestures such as pinch-to-zoom are not smooth at ThinkPad T420 stayed pleasantly cool throughout our testing. After streaming video for 15 minutes, the touchpad measured a frigid 82 degrees, the keyboard an icy 81 degrees, and the bottom a cool 87 degrees Fahrenheit. We consider temperatures below 95 degrees and AudioThe 230-nit, matte display provided sharp images and plenty of desktop real estate thanks to its optional 1600 x 900 panel. When we watched a 1080p QuickTime trailer for the movie Point Blank, images were sharp and motion smooth with viewing angles solid up to 45 degrees to the left or right. However, when we streamed a 720p Flash episode of Fringe from the edges of objects seemed a little pixelated, perhaps because the screen had a higher resolution than the video. We highly recommend the 1600 x 900 panel, a $50 option, because it shows a lot more of your favorite web pages and documents without forcing you to not as high fidelity as audio-focused consumer notebooks such as the Dell XPS and the HP Envy series, the Lenovo ThinkPad T420 provides surprisingly good music playback. Whether we were playing Kool and the Gang's jazz-oriented "Summer Madness," the bass-heavy "Between the Sheets" by the Isley Brothers, or Motley Crue's guitar-laden "Looks that Kill," sound was accurate and loud enough to fill a medium-sized room. We could even make out a solid separation of sound between the speakers, which sit on either side of the and WebcamThe ThinkPad T420 has plenty of connectivity options, but it's missing a couple of the obvious ones. On the right side are an Express Card 34 slot, a 4-in-1 memory card reader, a USB port, and a USB/eSATA port. On the back are a FireWire port and a powered USB port that allows you to charge devices with the system off. The left side houses VGA, DisplayPort, Ethernet, and one more USB port for a total of four. Conspicuously absent are USB ports and HDMI-out, neither of which are even available as options. Considering that we've been seeing notebooks with USB for over a year now and that Lenovo offers USB on many other ThinkPads the X1 and W520, for example, this is a pretty glaring 720p webcam provided sharp images even in low-light situations. In our dark living room, fine details of our face were visible when we snapped a picture at 1280 x 720 and chatted on Skype in standard def. However, like with many other webcams, our face appeared shadowy if there was a bright light source directly behind; this occurred when we tried snapping a photo while sitting in front of a window with sunlight coming conferencing software features a unique keyboard noise suppression feature that, on our tests, completely muted the sound of our typing as we chatted on Skype. The software also allows you to configure the dual-array microphones for a single voice or group its Core i5 CPU, 4GB of RAM, an Nvidia NVS 4200M graphics chip, and 7,200-rpm hard drive, the ThinkPad T420 was strong enough for anything we threw at it, from playing 1080p video to spreadsheet crunching and light gaming. On PCMarkVantage, which measures overall performance, the T420 scored a strong 8,197, much higher than the 5,596 thin-and-light notebook category average, the 7,728 turned in by the Toshiba Tecra R840, and the HP EliteBook 8460p both have the same Core i5-2520M CPU.The 500GB, 7,200-rpm hard drive booted into Windows 7 Professional in a speedy 48 seconds, much faster than the 65-second category average. The drive took a modest 3 minutes and 5 seconds to complete the LAPTOP File Transfer test, which involves copying of mixed-media files. That's a rate of MBps, a little higher than the 26 MBps category average but well behind the MBps provided by the Dell Latitude E6420 and its 7,200-rpm Oxelon Media Encoder, the T420 transcoded a 114MB MPEG4 to AVI in 43 seconds, 15 seconds less than the thin-and-light average, and on a par with the Toshiba R840 41 seconds and the HP 8460p 42 seconds.GraphicsOur ThinkPad T420 review unit came with Nvidia NVS 4200M and Intel HD 3000 GPUs and Nvidia's Optimus graphics switching technology to toggle between the two for the best combination of battery life and performance. On 3DMark06, which measures overall graphics prowess, the ThinkPad T420 scored a strong 5,583, well above the 4,006 category average, the 5,060 provided by the Dell Latitude E6420 with its Intel HD 3000 integrated graphics, and the 5,032 scored by the HP EliteBook 8460p with its AMD Radeon HD 6470M ThinkPad T420 isn't a gaming system, but its discrete graphics chip is good enough to get decent frame rates on some popular titles. At autodetect settings, the T420 provided a solid 61 frames per second when playing World of Warcraft, a little less than the 86 fps category average, but much higher than the 41 fps that the Dell Latitude E6420 got and the 52 fps scored by the HP EliteBook 8460p, and impressive given that most notebooks in the category have lower resolution screens. With special effects turned up, the rate dropped to a still-solid 32 the more demanding Far Cry 2, the ThinkPad T420 got a solid 37 fps at 1024 x 768 resolution, on a par with the fps category average. When we upped the resolution to 1600 x 900, that rate dropped to a modest 25 fps, which is comfortably above the 20 fps category LifeWith its nine-cell extended battery, the ThinkPad T420 lasts all day and then some. On the LAPTOP Battery Test, which involves continuous surfing over Wi-Fi, the notebook lasted a whopping 10 hours and 36 minutes, more than double the 515 category average and the battery life of the T420s 5 hours. That time is also significantly longer than the HP EliteBook 8460p 601 and the Toshiba Tecra R840 634. Only the Dell Latitude E6420 with its extended battery came close, lasting 8 OptionsThough our review unit carries an MSRP of $1,179, the ThinkPad T420 starts at just $789. For that price, you get a Core i3 CPU, integrated graphics, a 1366 x 768 display, but the same 500GB hard drive and 4GB of RAM as our review unit. If you want discrete graphics, you'll need to buy the $1,089 model that comes with a Core i5 CPU and 1600 x 900 screen, along with its Nvidia NVS 4200 GPU. Configuration options include a choice of storage 320/500GB hard drive or 128/160GB SSD, up to 8GB of RAM, a choice of Core i3, i5, or i7, and several different Wi-Fi cards. Strangely, the webcam and fingerprint reader are not standard, costing $20 and $30 matter what other options you choose, both the 1600 x 900 screen $50 and the nine-cell battery $50 are absolute musts for maximizing your productivity and Fingerprint Reader, and WarrantyLenovo bundles the ThinkPad T420 with the standard set of ThinkVantage utilities. Among these are the ThinkVantage Power manger, which allows you to exert fine control over the system's power profile. We particularly like the Instant Resume feature, which keeps the Wi-Fi card active for 10 or more minutes after you put the notebook to sleep so you don't have to wait for the system to reconnect after you wake utilities include Access Connections from managing your wireless connections, Password Manager, and Rescue and Recovery for Backups.

Business class. The ThinkPad T420s is mainly to convince business customers of its advantages as a powerful and yet portable companion. Equipped with a Core i7-2640M and a fast SSD from Intel as well as built-in UMTS, Lenovo has created good prerequisites for this another notebook range in the business sector enjoys such a high reputation as the ThinkPad models from Lenovo. The greatest robustness, high performance hardware and long battery runtimes are the qualities that let the manufacturer of the T series especially stand the following, we will examine to what extent the ThinkPad 420s can keep these promises. The T420s is a lot lighter and compacter than the previously reviewed T420 despite the same 14 inch size. However, it also has to manage with a smaller 44 Wh battery. While the immediate predecessor of the T410s still had processors from the Arrandale generation, the latest Sandy Bridge generation is now used. Our test device has been given the name ThinkPad T420s 4174-PEG NV8PEGE and represents the top model of the series. Lenovo hasn't made cutbacks in configuration and installs a Core i7-2640M and a fast 160 GB SSD from Intel. The HD Graphics 3000 integrated in the processor is additionally backed by a dedicated Nvidia Quadro NVS 4200M with Optimus support. The entry level models however don't have this feature. The manufacturer only skimps in view of the memory configuration and equips the nearly 1800€ notebook with only 4 competition in the battle for the favor of financially strong corporate customers is enormous. The ThinkPad T420s has to face devices like the Dell Latitude E6420, as well as the HP EliteBook 8460p. Our comprehensive review is to clarify if Lenovo can ultimately keep the T420s looks considerably slimmer and less unwieldy than its otherwise largely identical brother, T420. This is due to a weight of about kg and an overall height reduction of about centimeters. Lenovo has also maintained the classic ThinkPad design in the newest scion of its notebook range. Its appearance is dominated by plain but extremely robust, black plastic, reinforced with carbon fiber and magnesium, as in the past. The manufacturing quality is almost immaculate. We couldn't find any irregular gaps or deficient material transitions. The case only responds to very high force with marginal warping. We would only have liked to see a somewhat higher stability above the DVD drive. But the given level is exceptionally good. The torsional stiffness of the display and chassis is also impressive despite the low thickness. Regardless of all good qualities, we noticed that there is still room for improvements. The stability and quality of a MacBook Pro case, milled from aluminum, is yet unreached. That would also look good on the T420s. The aluminum display hinges make a very high-end impression. They allow the notebook to be opened to 180 degrees. Moreover, they keep the lid in place without prolonged shaking on shaky surfaces. Nevertheless, Lenovo has accomplished pulling the hinges only so tight that the notebook can be opened and closed with one hand. The display's clamshell design, known from other ThinkPads, prevents foreign objects and dust from unintentionally penetrating the gap between the keyboard and screen. Since the display overlaps the case, damages can successfully be prevented. The chassis's diet didn't go without affecting the T420s' connectivity. Only three USB ports have now found room on the case. That is two less than on the T420. In return, one of them is USB compatible and another has an always-on function. External monitors or projectors can either be connected over VGA or DisplayPort. On the other hand, Lenovo has left out HDMI which sooner used in the private customer sector. While Gigabit LAN, a 4in1 card reader SD/SDHC/SDXC/MMC and a combined headphone and microphone jack are still available, the combined eSATA/USB port has been omitted in the T420s. Additional interfaces can be added via an optionally available docking station. Only little has changed in view of interface distribution. All interfaces that are primarily needed for stationary use are found on the rear. That effectively counteracts the cable mess on the desk. Users who simply want to quickly connect a USB flash drive, a memory card or a headset can continue to do so on the device's left. Lenovo has also taken care to place all ports far enough apart so that even protruding plugs won't obstruct any neighboring interfaces. The notebook has a MP webcam with an average quality for video conferences. Audio is recorded via an array microphone and can convince with a clear and well-to-understand recordings. The so-called ThinkLight is a nice gadget. It's a small LED light beside the webcam that is to facilitate the T420s' use in dark surroundings. As a business laptop, the T420s can also serve with more features There is a Kensington Lock to protect the device against theft and the built-in fingerprint reader can be used for securing the stored data. The corresponding software is included in the preinstalled ThinkVantage Display lock Left Vent, USB audio, card reader Rear Power socket, LAN, USB always-on USB DisplayPort, VGA, vent Right WLAN slider, DVD burner, Kensington LockCommunication The T420s almost leaves nothing to be desired in our configuration. The Intel Centrino Ultimate-N 6300 module supports all current WLAN standards up to and also transmits in the 5 GHz network. Three antennas ensure an extremely stable connection even in cases of weak wireless signals. A Centrino Advanced-N 6250 with WiMAX support is alternately version takes care of data sharing with smartphones or other mobile devices in all models. Optionally available, and also installed in our test device, is a WWAN module Ericsson F5521gw which is capable of GPS and UMTS, including high-speed data transmission via HSPA+. The user can achieve gross data speeds of up to 21 MB/s in download and MB/s in upload with the right rate. The SIM card slot is hidden in the battery compartment, as in the ToolboxSupplies Lenovo doesn't include anything more than a quick start guide, the power adapter and the battery. Neither a driver nor a recovery CD is found. However, the user can create these from the backup partition of the T420s. Of course, all drivers and the ThinkVantage Toolbox are preinstalled in state of delivery. Warranty While American customers only receive a one year warranty ex-factory, all German devices have a 3 year onsite manufacturer the T410s or the T420, the tested T420s has the same combination of keyboard, touchpad and trackpoint. We will briefly summarize the most important qualities here. Keyboard The ThinkPad's keyboard bids high typing comfort, even for longer texts, with its firm and clear pressure point, its generous key drop for a laptop and the agreeably shaped keys. Yielding doesn't become evident even under high pressure at all; however the noise level could be a bit lower. The user is sufficiently compensated for this by an impression of an accurate, mechanical quality with every pressed key. The swapped position of FN and the left CRTL key may irritate the user at the beginning - a peculiarity that ThinkPads have had for years. Trackpoint Also unusual for a few, but a welcome tradition for the series, is the red trackpoint in the keyboard's lower center. After some getting used to, the user won't want to live without it because it allows just as a precise as fast control of the mouse cursor. Lenovo has given the trackpoint two dedicated mouse keys and a mouse wheel replacement located directly beneath the space bar. Thus, the user doesn't have to stretch his fingers up to the touchpad's keys beneath it. The click noise is very pleasant and quiet without lacking precision. Touchpad The touchpad's surface has a rough and distinctly different feel than the rest of the surrounding case. The finger glides pleasantly and smoothly over it and can control the mouse cursor with great accuracy. Multitouch gestures are supported, but it lessens the space on the already small touchpad gets even more. The corresponding buttons do their job quietly and reliably. However, they couldn't quite keep up with the quality of the other input devices and make a somewhat flimsy impression. It's possible to switch between the trackpoint and the touchpad via the key combination FN+F8. Both inputs can also be used uses a non-glare WXGA++ screen in all ThinkPads of the T420s range. The 1610 format of the T410s' predecessor had to make way for a wider 169 aspect ratio. Consequently, the former resolution of 1440x900 has increased to 1600x900 pixels. Together with a diagonal of inches, this results in an extremely high pixel density of 131 dpi. Unfortunately, the screen's measured rates aren't very impressive. Despite a good and even brightness of averagely cd/m2 in the highest setting, the contrast only equals a disappointing 1541. The reason for this is the high black value of cd/m2, which quickly leads to a rather grayish reproduction of black hues. 253cd/m²255cd/m²249cd/m²257cd/m²270cd/m²260cd/m²259cd/m²266cd/m²259cd/m² Distribution of brightnessAU Optronics B140RW02Gossen Mavo-MonitorMaximum 270 cd/m² Nits Average cd/m²Brightness Distribution 92 %Center on Battery 270 cd/m²Contrast 1541 Black cd/m² AdobeRGB 1998 Argyll 3D sRGB Argyll 3D Display P3 Argyll 3DThe low viewing angle stability is also on a level that seems inappropriate for this price range. While there is at least a certain amount of leniency for the viewer on the horizontal plane, deviations of only a few degrees lead to clear image distortions vertically. Unfortunately, the T420s isn't an isolated case. Immediate opponents, such as the Dell Latitude E6420 or the HP EliteBook 8460p also have similarly poor angles ThinkPad T420sRegardless of the partly only average results, the notebook can also be used outdoors without problems because of the matt screen surface and strong backlight. Although we would have also liked to see a screen with higher contrasts, the displayed content nevertheless remains legible even in direct we look at the ThinkPad's color reproduction. Both Adobe RGB and sRGB can't be covered completely, and even the larger T520 scores better here. Thus, a higher quality, external monitor should be connected over the available display port for professional image to GHz via Turbo BoostLenovo delivers the ThinkPad T420s with Intel's second generation Core i5 and Core i7 processors. As the top model of the series, our test device is equipped with a Core i7-2640M which is currently the fastest mobile dual core CPU on the market. Thanks to SMT Technology, every core can process two threads at the same time. The processor, manufactured in a 32nm process, is based on the latest Sandy Bridge architecture and has a base clock of GHz. It can be increased up to GHz via Turbo Boost The QM67 chipset, which also supports the processor-embedded HD Graphics 3000, is on the mainboard. The manufacturer has additionally installed an Nvidia Quadro NVS 4200M in a few versions of the series. It is enabled during an operation using Optimus when needed. Lenovo has given the T420s only one RAM module with a capacity of 4 gigabyte. Consequently, the processor also only has a single-channel memory bus available. Users, who need a larger RAM capacity and want to tickle out even the last percent of performance from the laptop, can retrofit another module in the second slot. However, the ThinkPad wasn't noticeably slowed down by the lack of dual-channel operation in our benchmarks. The highlight of all configuration features is undoubtedly the big 160 gigabyte SSD from Intel. It promises a significant performance increase in the system benchmarks. We will examine to what extent the swift memory unit is noticeable in practical information Lenovo ThinkPad T420s 4174-PEG CPU Performance Thanks to the generous hardware configuration, the T420s' performance rates are convincing. We determined the processor's single thread performance with Cinebench R10. The i7-2640M only lags behind the fastest mobile CPU, the Core i7-2960XM, by about 10% with 4450/5468 points 32/64 bit. A remarkable score for a CPU with a TDP of only 35 watts, which is mainly due to the strong Turbo mode of up to GHz. Our T420s has to admit defeat to the quad core competitors in the Multithreading Test of Cinebench An i7-2630QM is faster by more than 50% in view of points. This disadvantage however only has a negative effect when highly parallel and extremely CPU-heavy applications have to be processed. Beyond that, only the Dell Latitude E6420 is available with a quad core among the immediate opponents in the 14 inch R10 Rendering Single 32Bit4450 Cinebench R10 Rendering Multiple CPUs 32Bit9793 Cinebench R10 Rendering Single CPUs 64Bit5468 Points Cinebench R10 Rendering Multiple CPUs 64Bit11700 Points Cinebench R10 Shading 32Bit5015 Cinebench R10 Shading 64Bit5385 Points Cinebench CPU Multi Points Cinebench OpenGL fps HelpGPU Performance The dedicated Nvidia Quadro NVS 4200M was used for our benchmarks. It is automatically enabled in graphics load thanks to Optimus Technology. Benchmarks concerning the Intel HD Graphics 3000 integrated in the processor can be found in our database. The NVS 4200M is based on the GF119 chip, manufactured in a 40 nanometer process, and is also embedded on the entry level card, GeForce GT 520M. It has 48 shader ALUs and supports the current DirectX 11 standard. Lenovo has given the graphics chip a 1 gigabyte DDR3 memory on a 64bit wide memory interface; the clock speed is 740/1480/800 MHz core/shader/memory. This is a bit lower than the manufacturers specification of 810/1620/800 MHz, which results in a performance loss of about 10%. As expected, the card places itself approximately on the level of the identically clocked GeForce GT 520M and reaches 4829 points in 3DMark06. We could determine 2298 points in the performance preset with the successor, 3DMark Vantage. 3DMark 05 Standard 9388 points3DMark 06 Standard Score 4829 points3DMark Vantage P Result 2298 points3DMark 11 Performance 572 pointsHelp Gaming Performance Is this enough to also render newer games smoothly? The answer is a clear "yes and no". The demo version of newly released-building strategy game Anno 2070, used in the test, was only smoothly displayed in 1024x768 pixels and low details with fps. Thus, the NVS 4200M is only slightly faster than the Core i7-2640M's embedded graphics chip in this case. We could select medium or high details in older or less demanding games, like Fifa 12, but gamers won't be satisfied with the T420s' graphics performance. low med. high ultraAnno 2070 2011 CAD Performance This shortcoming won't likely be as devastating for the target group. Although the Quadro products are based on the same GeForce GPUs from Nvidia, these cards are specifically optimized for professional applications, such as from the CAD field. The low raw performance in the case of the NVS 4200M can only be compensated to an extent as can be seen in our very demanding benchmark, SPECviewperf 11System Performance The T420s achieves extremely good results in the system benchmark, PCMark, thanks to the fast processor and the SSD hard disk. With a total score of 11911 points in the Vantage version, the HP EliteBook 8460p 7734 points can be surpassed by 54%. 3312 points in PCMark 7 is also a very strong score. Even some gaming notebooks, like the Samsung 700G7A, don't manage that. Only larger laptops with a quad core processor and a high-end GPU can achieve better results 7 Experience IndexProcessorCalculations per RAMMemory operations per performance for Windows graphics3D business and gaming hard diskDisk data transfer PCMark Vantage Result 11911 pointsPCMark 7 Score 3312 pointsHelp AS SSDMass Memory In contrast to the entry level versions, our T420s test model comes with a 160 GB Intel SSD 320 series. The drive delivers an excellent presentation with sequential transfer rates of MB/s in read and MB/s in write CrystalDiskMark It can also excel with SSD-typical access speeds of milliseconds read/write. Now even faster drives with a SATA III interface are on the market. However, the solid state drives from Intel are deemed to be particularly reliable and are therefore an appropriate choice for the business laptop. Lenovo has branched off almost 16 gigabyte from the total capacity of 160 gigabyte for the recovery partition. The remainder is available for the operating system and other applications on a shared drive. The data memory's speed is already impressing when the preinstalled Windows 7 Professional as the 64bit version is booted The system is ready for use in less than 30 seconds after pressing the power button. Program installations and starts are accelerated significantly compared with a conventional hard disk. Moreover, no noise is generated and it has a lower power consumption. The user however has to accept a smaller capacity and a higher price in Read MB/s Sequential Write MB/s 4K QD32 Write MB/s System Noise ThinkPad users have high demands in an escort for everyday business regarding the noise of their work device. The fan of the T420s is usually deactivated in idle and light office tasks. Consequently, the notebook works absolutely noiselessly thanks to the SSD drive. Unfortunately, this condition doesn't last very long when the hardware is loaded a bit more, for example by a flash video. Despite uncritical temperature rates, the fan is turned on after a few seconds. It rotates fairly quietly and consistently, but it hums along audibly anyway. On the other hand, the ThinkPad is mostly unobtrusive during full load. We couldn't measure more than dB A even during our stress test with Furmark and Prime95 - a very good rate. Up until now, hardly a comparable device remained similarly quiet during this load. Even the Dell Latitude E6420 with a weaker Core i3-2310M climbed up to dB A.

We could measure temperatures of only 22-27°C without load. The notebook hardly gets lukewarm even directly at the vent. The case temperatures increase clearly after longer hardware load induced by our stress test and reach up to 39°C on the top. The cooling system can however keep a pleasant 28°C upright in the wrist rest and touchpad area. The bottom heats up to a very high 51°C selectively, but remains on a acceptable level on average. The maximum temperature of up to 99°C on the GPU and 96°C on the CPU is bordering. However, no stability issues developed in our multi-hour stress test and the processor only throttled marginally from GHz to GHz. The processor and graphics card remained a lot cooler in a realistic load induced by Cinebench or Anno 2070. Consequently, the device's cooling capacity should also be suitable for a warm summer. °C103 °C100 °C86 F °C94 °C79 °C83 F °C83 F28 °C82 °C78 F Maximum °C = 103 FAverage °C = 88 F °C85 °C110 F51 °C124 F29 °C84 °C98 °C95 °C78 F29 °C84 °C90 F Maximum 51 °C = 124 FAverage °C = 94 F Power Supply max. °C = 130 F Room Temperature °C = 67 F Voltcraft IR-360+ The average temperature for the upper side under maximal load is °C / 88 F, compared to the average of °C / 85 F for the devices in the class Office.+ The maximum temperature on the upper side is °C / 103 F, compared to the average of °C / 94 F, ranging from to °C for the class Office.- The bottom heats up to a maximum of 51 °C / 124 F, compared to the average of °C / 98 F+ In idle usage, the average temperature for the upper side is 25 °C / 77 F, compared to the device average of °C / 85 F.+ The palmrests and touchpad are cooler than skin temperature with a maximum of °C / F and are therefore cool to the touch. ± The average temperature of the palmrest area of similar devices was °C / 82 F °C / F. Speakers The T420s has two small stereo speakers, which are hidden behind a lattice on the keyboard's left and right. Not much has changed in regards to the mediocre sound quality of other ThinkPad range models. Midranges could already only be played insufficiently from the small speakers, and we didn't notice any basses. Speech is rendered somewhat tinny, but intelligibly and without distortions providing the user doesn't exceed a low volume. Otherwise it is advisable to connect an additional sound system using the headphone out, which succeeded with good quality in the Consumption The ThinkPad T420s' power consumption isn't conspicuous. 10 to 16 watts in idle aren't a record for a laptop with Optimus support, but are within an acceptable limit. The power requirement clearly increases in full load. We could measure a maximum of watts in the unrealistic stress test with Prime95 and Furmark. In view of the installed hardware and the only marginal throttling, it's a good rate. The Dell Latitude 6420, which was even more energy efficient in idle, consumed a bit more despite a weaker processor in this case watts. The included 90 watt power adapter has a sufficient capacity to charge the battery even during 6 cell battery now only has a capacity of 44 Wh due to the T420s' slim case, while the T420 had 57 Wh. The laptop managed a battery runtime of over 6 hours in the Battery Eater Reader's test, which simulates the notebook's idle mode in minimum brightness. So about 2 hours more than the previous T410s. Surfing via WLAN also proves that the new Sandy Bridge range is more energy efficient than the former Arrandale processor with a battery life of almost 4 hours. The T420s can't hide its powerful hardware and had to give up after 42 minutes in Runtime Idle without WLAN, min brightness 6h 16min WiFi Surfing 3h 57min DVD 2h 55min Load maximum brightness 0h 42min Lenovo Thinkpad T420sLenovo hasn't really launched a new product onto the market with the T420s. No matter if it's the classic ThinkPad case design, the excellent input devices or the installed hardware, we have seen almost all of these model characteristics in the sister model, T420, or the previous T410s. Nevertheless, the T420s occupies a market niche that is supposed to especially address business customers with its combination of high performance components and high mobility. They will likely be pleased about a fast Core i7, an SSD drive and an extensive connectivity including UMTS/HSPA at a price of just under 1800€. The manufacturing quality and case stability is high-end, but is surpassed by a few competitors, such as the HP EliteBook 8460p. We noticed room for improvement in the fan management's fine-tuning and the built-in screen. The latter is suitable for outdoor use due to its matt surface and good brightness, but is very viewing angle dependent and has a disappointing black value. Overall, the Lenovo ThinkPad T420s earns itself a good, though not very good total score of 84%. In addition to the EliteBook 8460p from HP, the Dell Latitude E6420 could be a possible alternative. It can achieve a battery life of up to 12 hours due to an optional 9 cell battery. By courtesy of...

It has the battery life, usability and build quality it takes to get work done around campus. The option of configuring either a budget level laptop of around $800 or high-end laptop configuration of $1,400+ is great and allows you to design a laptop that fits your needs, but still get the same build and design quality no matter what you include. I like the fact the option for a higher resolution screen is present, for those of us that find we can do work more efficiently using two windows open at once on the screen you will appreciate the 1600 x 900 resolution screen.
