Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 25510 Hz | ≤ 50 % brightness setting |  |
The display backlight flickers at 25510 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 50 % 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. | |||

Pros
Cons
联想ThinkPad A285终于让用户有机会体验配备AMD处理器的紧凑型ThinkPad笔记本电脑。除了三个基本型号外，这台12.5英寸的设备还可拓展诸如SmartCard读卡器或指纹扫描仪等实用功能。制造商还提供可选的WWAN模块，因此您可以在旅途中使用互联网。
AMD的Ryzen 5 Pro 2500U是A285的优秀CPU，为日常任务提供了充足的性能。该处理器可与英特尔酷睿i5-8250U相媲美，但不适用于持续工作负载。配备Intel CPU的X280速度更快，但这也是由联想设置的不同TDP的结果。
两个处理器之间最大的区别是集成显卡。AMD的Radeon Vega 8性能强得多可以在基准测试中轻松击败英特尔UHD 620。
我们联想ThinkPad A285零售价为5999元。我们特别喜欢其出色的输入设备，256 GB PCIe-SSD可确保高传输速率，从而获得良好的系统性能。高品质和坚固的机身更是锦上添花。它的重量仅为1.1千克，因此您可以轻松携带它或将其放入包中。
“联想ThinkPad A285是一款基于AMD处理器的优质办公设备，与X280相比价格更低。如果您不需要X280的额外CPU性能或更长的续航时间，A285是一个不错的选择。”
但此机器仍然存在一些缺点，例如高功耗，与X280相比，这会影响续航时间。我们测试机上的屏幕也有点差，但这是联想“抽奖”的结果。由于制造商使用了不同的供应商，您永远不知道您将获得哪块屏幕。
板载内存对于商务本来说绝对不是好事，这意味着你以后无法升级。A285也缺乏X280的雷电3支持。尽管如此，该设备的整体印象还是不错的，我们可以推荐它。用户是否愿意为他们的商务本切换到AMD硬件仍有待时间考验，但更低的价格绝对是一个优势。性能差不多的ThinkPad X280配备英特尔CPU，价格上则贵了800元。
