笔记本电脑突然关机。最初，这种情况发生在笔记本电脑未使用时，但最近，即使我正在使用它，这种情况也开始发生。我的笔记本电脑很旧了。我尝试查看 kern.log 和 syslog。我尝试查看这是否是过热问题，但无法确认。

我是 Linux 新手，无法弄清楚这一点。请帮忙！
编辑我读了一个类似问题的答案并使用了命令“
sudo journalctl -b -1 -e
查看上一次启动日志的结尾。我不太明白。我想我会添加它以防有帮助。
编辑：我重新安装了 Ubuntu 22.04。这些是我使用 journalctl -b -1 -e 命令获得的日志。我使用相同的命令删除了我提供的日志以保持在字符限制内。
