联想IdeaPad S540-15IWL笔记本电脑评测：只有一个真正缺点的全能本

Name: Lenovo IdeaPad S540-15IWL 81SW0015GE
Brand: Lenovo

差点成为超极本。

15英寸全能本在优雅纤巧的铝制外壳中配备了GTX 1650 Max-Q，并在测试中具有许多积极的价值，从而引起了人们的注意。例如明亮的高对比度显示屏和快速的SSD。但是，它也显示出明显的弱点。

Display Response Times

ℹ

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
29.6 ms ... rise ↗ and fall ↘ combined	↗ 16.4 ms rise
29.6 ms ... rise ↗ and fall ↘ combined	↘ 13.2 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 77 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
39.2 ms ... rise ↗ and fall ↘ combined	↗ 21.2 ms rise
39.2 ms ... rise ↗ and fall ↘ combined	↘ 18 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 56 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.9 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

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

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 8774 (minimum: 5 - maximum: 343500) Hz was measured.

The Lenovo S540-15IWL, test unit provided by campuspoint

联想带来了一款表现良好的机子，对于真正的全能来说应该就是这样的，但竞争对手却很少做到：出色的显示屏，非常快的SSD，高效的组件，优雅的设计以及易于维护的功能（如果您有一把Torx螺丝刀）只是其中一些优点。

当然，IdeaPad也有一些缺点，但是大多数缺点微不足道，例如缺少网线接口，性能由于散热略有下降以及缺少第二个RAM插槽。但是，我们确实需要指出一个明显的弱点：尽管相比之下，联想使用的是最安静的散热系统之一，但是主观上来说非常令人不快的高频风扇噪音却无法抵消这种积极影响。这应该由制造商纠正！不过，学生和其对缺点他不太敏感的人可能花1100欧元（〜1203美元）就买到它。

那些对高频风扇噪音不太敏感的人将获得一台15英寸的平衡型全能笔记本电脑，该笔记本电脑具有出色的组件和出色的工艺。
