我的 openSUSE 15.2 笔记本在过去四个星期内经历了 3 次意外关机。我所说的意外关机是指系统在我无意中突然关闭，就像突然断电一样。在每种情况下，电池都至少有 70% 的电量，或者（就像今天一样）笔记本电脑已连接到扩展坞。 （该系统推出还不到 6 个月。）
当这些断电发生时，系统没有运行任何繁重的任务，RAM (32 GB) 还没有满，运行的应用程序通常是 Firefox（最多有几十个选项卡）、Skype 、编程编辑器（通常是 Geany；上次也是 jEdit）、Dolphin（在 KDE 下）以及（上次，但不是今天）LibreOffice 和 Terminator。我经常让 VeraCrypt 运行，但今天断电时它没有运行。换句话说，我无法根据正在运行的应用程序来解释电源关闭。
今天，我查看了日志文件（今天var/log已更改的日志文件），例如lastlog、wtmp、snapper.log和，并且我还查看了 的转储，但我不确定要查找什么。warnmessagessudo journalctl --since today > /home/.../journalctldump
我var/log/warn在关闭电源时发现了类似以下内容的行：

其中几行包含诸如“unable”、“failed”或“fatal”之类的字符串，但我不知道它们中是否有任何一个指向可能导致突然关闭的东西。是否有可能通过检查日志文件来找到这些断电的原因，或者这是一项无望的任务？
