| The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 48 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (33.7 ms). | ||
Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 25000 Hz | ≤ 40 % brightness setting |  |
The display backlight flickers at 25000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 40 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 25000 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 17900 (minimum: 5 - maximum: 3846000) Hz was measured. | |||

Veredicto - Mais forte ou mais fraco que o L480?
Como um computador de escritório e de trabalho, a Lenovo continua errando um pouco com o ThinkPad L490. Escrever com o teclado ainda é rápido e agradável, e a velocidade de trabalho é decente em geral.
No entanto, você precisa dar uma olhada nos detalhes para não perceber a atualização de hardware deste ano como algo supérfluo. Dado que as alterações evidentes - ou seja, a nova tela e o processador Whiskey Lake - não saíram como desejado. A CPU é afogada e, portanto, é mais lenta que a Kaby Lake no predecessor. A tela troca um pouco mais de brilho por um contraste e um valor de preto mais fracos.
Por outro lado, a Lenovo finalmente está incluindo um SSD mais rápido, o Bluetooth 5 está agora a bordo e o computador móvel geralmente é confortavelmente silencioso. Não gostamos muito do sistema de resfriamento; ele se entrega repetidamente a fazer pausas, mesmo sob uso intenso. Mas o silêncio agradável, infelizmente apenas temporário, acontece em detrimento do desempenho e gera temperaturas altamente flutuantes.
O Lenovo ThinkPad L490 continua a impressionar como um portátil de escritório muito bom. Seus dispositivos de entrada, a boa duração da bateria e, finalmente, também um SSD mais rápido tornam o portátil um computador de trabalho apto para empresas, estudantes e qualquer outra pessoa que lida com a escrita e a Web.
Mas, na verdade, não é nada fácil outorgar uma recomendação clara de compra, pois, por um lado, o L490 se diferencia do predecessor com muitos poucos benefícios, e por outro lado, está muito perto do E490. Com o último, aqueles que podem ficar sem um slot ExpressCard obterão a tela consideravelmente mais brilhante e mais rica em contraste com o mesmo desempenho e uma duração de bateria igualmente boa a um preço presumivelmente mais favorável, pelo menos fora do desconto especial para estudantes. Por 699 Euros (~$771), este último pode apertar o gatilho de compra sem hesitação.
