Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 25510 Hz | ≤ 20 % brightness setting |  |
The display backlight flickers at 25510 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 25510 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 8743 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Verdict - A good all-rounder with one significant weakness
A Lenovo oferece um pacote geral coerente, que é como deveria ser para um verdadeiro polivalente, mas raramente é alcançado pelos concorrentes: Uma ótima tela, um SSD muito rápido, componentes eficientes, um design elegante e fácil manutenção (se você tiver uma chave de fenda Torx) são apenas algumas das vantagens que vale a pena mencionar.
Obviamente, o IdeaPad também possui alguns pontos fracos, mas a maioria deles é mínima, como a falta de uma conexão LAN, pequenas quedas de desempenho (devido ao resfriamento) e a falta de um segundo slot de RAM. No entanto, precisamos apontar uma fraqueza significativa: Embora a Lenovo use um dos sistemas de refrigeração mais silenciosos em comparação, esse efeito positivo mensurável é desfeito por um ruído de alta frequência subjetivo e desagradável do ventilador. Isso deveria ser remediado pelo fabricante! Por outro lado, estudantes e outras pessoas que não são muito sensíveis podem querer comprá-lo por cerca de 1.100 Euros (~$1.203).
Aqueles cujos ouvidos são menos sensíveis ao ruído agudo do ventilador obterão um portátil versátil e equilibrado com o IdeaPad S540 de 15 polegadas, que oferece ótimos componentes e bom acabamento.
