联想 ThinkPad 13 Chromebook 笔记本电脑简短评测

Name: Lenovo ThinkPad 13 Chromebook
Brand: Lenovo

实用且实惠？ 几个月之前，我们测试了入门级的ThinkPad 13，它的表现十分不错。今天，来到我们实验室的则是它的Chromebook版本。它可以成为Windows世界的一个替代吗？

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
36 ms ... rise ↗ and fall ↘ combined	↗ 5.2 ms rise
36 ms ... rise ↗ and fall ↘ combined	↘ 30.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 93 % 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
37.6 ms ... rise ↗ and fall ↘ combined	↗ 15.2 ms rise
37.6 ms ... rise ↗ and fall ↘ combined	↘ 22.4 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. » 50 % 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 not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8746 (minimum: 5 - maximum: 343500) Hz was measured.

In review: Lenovo ThinkPad 13 Chromebook. Test model courtesy of Lenovo US

联想的全新ThinkPad 13 Chromebook几乎实现了所有的ThinkPad核心理念。它设计实用，搭配了坚固而符合人体工学设计的机身，有近乎完美的输入设备，同时保证了出色的电池续航时间。同时它还搭配了相当不错的屏幕，强劲处理器和大容量双通道内存则带来了流畅的使用体验。许多这些功能都很难在Chromebook中找到，不过随着平台的逐渐发展应该也会有更多的选择对它发起挑战。

最大的问题还是这些功能是否真的对于一台Chormebook来说有意义，不管怎么说对于这类设备来说至今为止最常见的原则还是实惠和简单。后者对于ThinkPad 13 Chromebook仍然适用，不过考虑到我们测试机的配置——极速酷睿i5处理器和8 GB内存——它的售价则达到了845美元（约5644人民币）。这仅比配置更高的Windows系统ThinkPad 13便宜100美元（约667人民币），而另外这款机型则搭配了256 GB固态硬盘而非32 GB eMMC闪存，它也提供了更好的可维护性。更不用提Windows相比Chrome OS更高的附加价值了；不论Chrome系统如何发展，一些限制如原生打印支持和对很多应用程序的支持都会限制商务用户的选择。
