今天我打开了我的电脑，在开机工作流程中它断电了几次。
我检查过日志，但没有找到原因，我大约在 14:00 左右开机（几次才成功开机）。
意外断电发生在不同的时刻：系统加载后、屏幕上显示 GRUB 菜单后、输入密码后、X-Window 管理器加载后、旧浏览器会话重新启动后、或者新的互联网页面开始打开时。
然后就一直工作到现在。
在下面的列表中，它显示了 14:13 启动后的几行，以及 14:19 新启动之前的几行，它在外部断电前大约 6 分钟工作，所以它可能总结了原因，但我还没有找到错误消息如
：因为...原因电脑断电或其他原因。
我读过 manjournalctl，只是我不知道，我需要找到什么主题？
如何找到正确的意外断电原因？
下面我列出了今天第一次开机的日志，其中包括启动和正常工作流程直到晚上的所有短时间段

这是下次启动之前的几行，因此可能可以推断出断电原因，但我不明白，哪个？没有任何错误消息
