联想Flex 3Chromebook 11M836评论。廉价且实用

由联发科驱动的机器。

一款不折不扣的可转换Chromebook ，专为小学生、旅行或次要的备份笔记本电脑设计。如果你能克服笨重的尺寸，它就会相对结实。

Chromebook Touchscreen Convertible / 2-in-1

大约200至300美元，联想IdeaPad Flex 3Chromebook 11是市场上最便宜的Chromebook 2合1产品之一。该系统由同样的八核联发科MT8183 SoC驱动，为宏碁Chromebook Spin 311和 2019年亚马逊Fire HD 10平板电脑。所有SKU都配备了联发科SoC、4GB LPDDR4X内存和11.6英寸768p触摸屏，以及32GB或64GB的不可拆卸eMMC存储。

替代品包括 AcerChromebook Spin 311, 惠普Chromebook x2 11, 联想IdeaPad Duet, 或华硕Chromebook Flip.

案例

考虑到低廉的要价，建造质量要比预期的好。然而，主要的缺点是，该系统较大，因此对其尺寸级别来说较重。例如，Chromebook C330和Chromebook Spin 311，都是13.3英寸的Chromebook，但它们的重量几乎与我们的11.6英寸的Flex 3相同，只是尺寸稍厚。学生们可能会喜欢Flex 3可以承受一些打击，但旅行者可能想要一些相对于屏幕尺寸更轻的东西。

虽然屏幕尺寸为11.6英寸，但由于边框非常厚，该系统感觉像是一台13.3英寸的笔记本电脑。

连接性

端口选项与宏碁Chromebook Spin 311相似。请记住，没有HDMI端口，因此任何外部显示器必须通过唯一的USB-C端口连接。请确保外部显示器支持USB-C充电直通，否则你将无法同时为系统充电和输出到外部显示器。

SD卡阅读器

集成的MicroSD读卡器是相当慢的。将1GB的图片从我们的UHS-II卡移动到机器上需要大约55秒，而在联想Chromebook C330或宏基Chromebook Spin 511上则需要40秒。

沟通

传输速率很稳定，但有点慢，平均下载速率只有263Mbps。值得庆幸的是，这对于720p或1080p的流媒体来说是绰绰有余的。

网络摄像头

网络摄像头是标准的低质量的720p的事情。手动隐私快门是标准配置，因此用户不需要用胶带封住摄像头。

维护

如果你有一把T5 Torx扳手，底板很容易拆下来。不过，除了电池之外，没有什么可以维修的。

配件和保修

除了文件和交流电适配器外，盒子里没有任何额外的东西。通常的一年有限保修期适用。

输入设备

键盘

大多数Chromebook上的键盘给人的感觉几乎都是一样的，特别是因为谷歌在按键布局方面有严格的标准。不幸的是，没有背光选项。

触摸板

点击板很小，为10.5 x 6.2厘米。中高速时牵引力平稳，慢速时相对粘滞。同时，在点击板上的点击是比较浅的，有弹性的。

显示

768p的低原始分辨率是廉价的11.6英寸Chromebook的典型特征。尽管屏幕面积有限，但对比度和响应时间实际上是相当可观的，因为黑色相对较深，重影减少。因此，视频和游戏流等多媒体播放在这台廉价的Chromebook ，看起来还不错。

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
16 ms ... rise ↗ and fall ↘ combined	↗ 15.2 ms rise
16 ms ... rise ↗ and fall ↘ combined	↘ 10.8 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. » 33 % of all devices are better. This means that the measured response time is better than the average of all tested devices (21 ms).
↔ Response Time 50% Grey to 80% Grey
26 ms ... rise ↗ and fall ↘ combined	↗ 12.4 ms rise
26 ms ... rise ↗ and fall ↘ combined	↘ 13.6 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 0.165 (minimum) to 636 (maximum) ms. » 32 % of all devices are better. This means that the measured response time is better 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 8734 (minimum: 5 - maximum: 343500) Hz was measured.

户外能见度比较暗的宏碁Chromebook Spin 311或联想Chromebook C330好，但比较亮的惠普Chromebook x2和 AcerChromebook Spin 713.即使在最好的条件下，也会出现一些轻微的眩光。

业绩

处理器

原始的CPU性能大约要比现在慢25%。 Exynos 9611去年的 Galaxy Tab S6 Lite.该处理器无法以60 FPS的速度流畅地传输4K视频内容；我们用1分钟的4K60 YouTube视频进行测试，会导致近1500个丢帧。否则，通过Chrome OS进行导航是非常顺利的，没有任何重大的性能问题。

在最大音量下的粉红噪音显示出糟糕的低音再现。对于11.6英寸的小屏幕尺寸来说，最大音量还算不错

能源管理

消耗功率

在最低的亮度水平设置下，在桌面上空转只需要0.8瓦。如果设置为最大亮度，消耗量将猛增3瓦。视频流大约需要5.4瓦，而在运行CPU基准测试时，最大可以达到8.9瓦。结果与我们在宏碁Chromebook Spin 311上记录的结果相似，后者与我们的联想一样，都有11.6英寸的屏幕尺寸和联发科SoC。

小巧的（约9.2 x 3.9 x 2.9厘米）45瓦交流适配器为联想Chromebook ，提供了足够的电力。这个适配器也可用于为其他USB-C设备和笔记本电脑充电。

电池寿命

在需要充电之前，用户可以期待超过13小时的实际浏览时间。值得庆幸的是，该系统可以支持大多数的USB-C充电器，因此用户不需要担心任何专有的桶状适配器。

使用附带的USB-C交流适配器，从空电到满电的充电速度很快，约为90分钟。

判决书

联想Flex 3 Chrome是一个更好的Chromebook ，比AcerChromebook Spin 311.它的显示屏更亮，响应时间更快，而机箱为有需要的人集成了一个MicroSD读卡器。它的厚皮设计允许比你典型的更薄的超极本或平板电脑更多的碰撞和挫伤，如惠普Chromebook x2.

笨重的设计是Flex 3 Chrome的主要缺点。虽然这是一台11.6英寸的笔记本电脑，但厚厚的边框使该系统感觉像是一台13.3英寸的笔记本电脑。这对学生和一些旅行者来说可能是可以接受的，但更轻的东西，如联想IdeaPad Duet或前面提到的惠普Chromebook x2在某些情况下可能更受欢迎，即使它们更脆弱。
