富士通 LifeBook E557 (i3-7100U, HD620) 笔记本电脑简短评测

Name: Fujitsu Lifebook E557
Brand: Fujitsu

老套。 这种情况不常有，笔记本电脑允许用户更换电池，而不必将整个电池拆开。可拆卸的外壳，确保了用户能够更换每个可更换部件。最后，时下流行的接口都不存在。我们今天的测试机就是这样一台电脑。那么问题是：它还能提供什么呢？

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
26 ms ... rise ↗ and fall ↘ combined	↗ 22 ms rise
26 ms ... rise ↗ and fall ↘ combined	↘ 4 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. » 59 % 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
50 ms ... rise ↗ and fall ↘ combined	↗ 30 ms rise
50 ms ... rise ↗ and fall ↘ combined	↘ 20 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. » 84 % 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

210 Hz

≤ 90 % brightness setting

The display backlight flickers at 210 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 210 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

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.

Verdict

Our test device was provided to us courtesy of: AfB social & green IT

LifeBook E557通过其模块化设计和特殊界面来突显自己，这样的设计目前并不容易找到。790欧元（917美元）的价格下，提供着不错的性能。不过，富士通在外壳用料上节约了太多成本。设计可以被描述为“复古”。这些材料看起来很廉价，但其他一切看起来都很坚实耐用。优点在于，所提供的维护性，是我们所喜欢的。

总的来说，LifeBook E557通过外观的差异和易于维护性，差异化自己。

对于消费者来说，如果他可以忍受较差的用料，而且需要一台设计特别的电脑，LifeBook E557值得考虑。我们测试机的硬件，为日常任务提供了足够的性能。而那些愿意花更多钱的人，同样可以获得更好的显示效果和更快的处理器。
