| Screen flickering / PWM detected | 2451 Hz | ≤ 50 % brightness setting |  |
The display backlight flickers at 2451 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 50 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 2451 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Contra
No papel, é claro que o Lenovo ThinkPad T490 é o sucessor do ThinkPad T480. Mas, na realidade, o design do ThinkPad T490 é radicalmente diferente, o que torna apropriado chamá-lo de uma mistura do T480 e do T480s em vez de um sucessor direto para o T480. Essa combinação é muito bem feita, mas também há pontos fracos.
O ThinkPad T490 tem uma carcaça robusta feita de plástico reforçado com magnésio, que é muito mais leve e compacta que a carcaça do T480. As opções de conectividade são abundantes, assim como os recursos de segurança disponíveis e as opções de comunicação com o RJ45 de tamanho completo, além do LTE (opcional), além do Wi-Fi. Como é típico para um ThinkPad, os dispositivos de entrada são muito bons. A maior melhoria em comparação com as antigas gerações do ThinkPad está relacionada à tela. Finalmente, a Lenovo coloca uma tela FHD de alta qualidade com um bom brilho de tela e gama de cores. O desempenho da CPU do ThinkPad T490 está acima da média graças ao TDP mais alto e a Nvidia GeForce MX250 opcional, permite até mesmo alguns jogos leves, tornando o T490 ainda mais flexível. Apesar do bom desempenho, os ventiladores do ThinkPad T490 são silenciosos, e a duração da bateria é boa. Por último, mas não menos importante, o pacote de garantia do T490 que testamos, é generoso.
Embora a tela seja um dos melhores argumentos para o ThinkPad T490, seus tempos de resposta são extremamente ruins e os movimentos rápidos do cursor resultam em fantasmas. O T490 tem muitas portas, mas infelizmente, a Lenovo substituiu o slot para cartão SD com um slot para cartão microSD - uma mudança desnecessária em nossa opinião. Também é lamentável que a porta Thunderbolt 3 esteja conectada através de apenas duas pistas PCIe. De todos os recentes ThinkPads T/X com tela de 14 polegadas, o T490 é o modelo mais atualizável, mas é difícil abrir e fechar a carcaça. As altas temperaturas sob carga também são problemáticas, pois elas cruzam o importante limiar de 50 °C (122 °F). O bom desempenho e o ventilador silencioso têm seu preço, afinal, dado que o T490 também se afoga no teste de estresse. Outro problema do T490 é o ruído que emite: É atormentado pelo ruído do alto-falante e da bobina. Finalmente, lamentamos a perda do recurso PowerBridge - as baterias USB C podem ter a mesma função, mas o PowerBridge era um recurso interessante e confortável.
O Lenovo ThinkPad T490 é o mais novo modelo da série T tradicional - a Lenovo fez muitas alterações em comparação com o modelo anterior. Embora nem todas essas mudanças tenham sido boas, considerando tudo, o ThinkPad T490 é um melhor portátil que o T480.
No geral, o Lenovo ThinkPad T490 é um portátil corporativo muito bom, mas a Lenovo deve consertar o alto-falante com uma atualização de software. Além disso, a questão é quão bem o sistema de resfriamento iGPU mais fraco pode resfriar o processador. Nós damos ao ThinkPad T490 uma recomendação básica, mas os usuários devem escolher um modelo com a tela FHD de baixa potência ou o LCD QHD.
