Breve Análise do Portátil Lenovo IdeaPad S540-15IML: Excelente duração da bateria

Florian Glaser, Andrea Grüblinger (traduzido por Ricardo Soto), 01/28/2020

Espelho, espelho na parede. O IdeaPad S540-15IML de 15 polegadas não apenas impressionou em nosso teste com uma carcaça de metal de alta qualidade, mas também com uma excelente duração de bateria. No entanto, realmente não conseguimos entender por que a Lenovo optou por uma tela brilhante.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
34.8 ms ... rise ↗ and fall ↘ combined↗ 18.8 ms rise
↘ 16 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 90 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.9 ms).
       Response Time 50% Grey to 80% Grey
49.6 ms ... rise ↗ and fall ↘ combined↗ 22.4 ms rise
↘ 27.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 82 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39.6 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 202 Hz ≤ 99 % brightness setting

The display backlight flickers at 202 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 202 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 13646 (minimum: 43 - maximum: 2500000) Hz was measured.

- Muito poucas conexões
- Tela muito refletiva

Lenovo IdeaPad S540-15IML, review device provided by:

Um campeão de resistência com uma elegante carcaça de metal por 800 Euros (~$882)? O que parece improvável a princípio é uma realidade com o Lenovo IdeaPad S540-15IML.

Dificilmente qualquer outro portátil versátil se comporta tão bem sem uma fonte de alimentação. Juntamente com o baixo peso (1,9 kg) e a construção plana (1,7 cm), o equipamento de 15 polegadas é predestinado para uso móvel.

Se apenas a tela refletiva que frustra as atividades ao ar livre, e até muitas atividades internas, não estivesse ai. Um painel mate seria muito mais adequado para o dispositivo e, acima de tudo, mais adequado ao conceito geral.

Se você pode aceitar essa falha, no entanto, receberá um portátil multimídia recomendável e muito bem-sucedido.
