联想IdeaPad Slim 1-14AST-05笔记本电脑评测：带了Office 365的Chromebook竞争者

Name: Lenovo IdeaPad Slim 1-14AST-05
Brand: Lenovo

挺慢的。 联想的14英寸笔记本电脑可能会使Chromebook的情况变得困难。该设备有着优秀的键盘和为期一年的MS Office 365个人许可证。计算能力和内存容量并不令人信服。但是Ideapad的价格不到280欧元。

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
14 ms ... rise ↗ and fall ↘ combined	↗ 10 ms rise
14 ms ... rise ↗ and fall ↘ combined	↘ 4 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 29 % of all devices are better. This means that the measured response time is better than the average of all tested devices (21.5 ms).
↔ Response Time 50% Grey to 80% Grey
44 ms ... rise ↗ and fall ↘ combined	↗ 24 ms rise
44 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 0.2 (minimum) to 636 (maximum) ms. » 70 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (33.7 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

147 Hz

≤ 60 % brightness setting

The display backlight flickers at 147 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 60 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 147 Hz is very low, so the flickering may cause eyestrain and headaches after extended use.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17900 (minimum: 5 - maximum: 3846000) Hz was measured.

联想IdeaPad Slim 1-14AST-05笔记本电脑评测, provided by:

即使价格（280欧元）似乎很诱人，您也应该三思。这台笔记本计算机的性能会很快达到其极限，并且反应迟钝。也没有任何方式可以加快其速度。

Ideapad Slim 1-14AST-05作为Chromebook的竞争对手并没有令人信服的形象。 Chromebook通常可以更流畅地使用-即使是硬件较弱的型号。

联想决定结合使用性能较差的APU，4 GB RAM和eMMC模块，而Windows 10则使该配置负担很大。该设备最多只能用于打开一个应用程序或网站。屏幕非常低档-这里的关键词是暗，低对比度，不稳定的视角。没有足够的存储空间（初始设置后大约33 GB）。联想否认我们的测试设备可以安装SSD。仅保留通过MicroSD卡进行的内存扩展。

可以说一些积极的事情。联想为Ideapad授予两年保修。不发光的Chiclet键盘给人留下了深刻的印象，也适合进行常规打字工作。还包括价值近70欧元的一年期MS Office 365个人许可证。

因此，Ideapad可作为学生的廉价打字机。但是，它缺乏长久使用能力。 Ideapad在5:39小时后结束了我们实际的WLAN测试（模拟使用脚本调用网页时的负载）-对于学校或大学使用来说，时间太少了。在此，必须始终随身携带充电器。
