Screen Flickering / PWM (Pulse-Width Modulation)
| 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 8706 (minimum: 5 - maximum: 343500) Hz was measured. | |||

Verdict
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。
