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。
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。

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。

Cons
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。
