我在 Ubuntu Desktop 20.04 上安装了 LENOVO ThinkPad L13 Yoga。
几天来，Ubuntu 一直崩溃并突然关闭。
查看日志journalctl显示问题出在过热，
Jun 30 13:13:18 siavash-fra thermald[1184]: critical temp reached
Jun 30 13:13:19 siavash-fra thermald[1184]: critical temp reached
-- Reboot --
虽然没有过热的迹象。所以我用 监控温度sensors。以下是启动后没有运行任何任务后的值：

但是，当我运行一个 Python 脚本时，不到两秒钟温度就达到临界值并且崩溃了：

实际上感觉不到任何温暖。这可能是错误信号吗？温度能在不到 2 秒的时间内达到如此高的温度吗？
我同时使用 Windows，没有出现过热或崩溃的情况。顺便说一句，它显示了，fan1: 0 RPM但我能听到并感觉到风扇在运转。
