我有一台戴尔 inspiron 13 7368，运行 Ubuntu 16.04 一切都很好，很顺利，除了它不止一次发生过突然关机的情况，就像如果你在没有电池的情况下拔掉电源一样，当这种情况发生时它总是靠电池运行。
有什么建议吗？在哪里查看或测试什么？

听起来像是电池坏了。但让我们尝试重置电源管理器。
拔下电脑的交流电源插头，取出电池（如果电池可拆卸）。按住电源按钮 10-15 秒。重新安装电池并重新连接交流适配器（如果您愿意），看看这是否能解决您的关机问题。
more /var/log/syslog您还可以通过在终端中输入并查找关机时间附近的内容来检查系统日志文件。特别查找任何与温度相关的消息。如果找到，则表明您的机器过热，导致关机。
还有一个 BIOS（和固件）更新可能会有所帮助。请参阅http://www.dell.com/support/home/us/en/04/product-support/product/inspiron-13-7368-2-in-1-laptop/drivers，并选择 BIOS（或全部）作为类别。
干杯，艾尔
