我的问题是处理器一直过热。温度在 60°C 到 85°C 之间，而且很少有程序在运行。

使用 Windows 时机器不会过热。

答案1

我的 Lenovo T500 和 Ubuntu 12.04 也存在同样的问题。我唯一能用的版本是 10.04。有了它，我的笔记本电脑就不会过热了。从那时起，我就一直有问题。甚至 jupiter 或 indicator-cpufreq 都无济于事。问题在于，过热的不仅仅是处理器，而是整个笔记本电脑。当我运行 Windows 时，我的笔记本电脑会凉爽得多。我的看法是内核仍然存在一些问题。对我来说，唯一的解决方案是在 BIOS 中设置 AC - 省电模式。但这只能解决处理器的温度问题。

答案2

我建议你使用cpufrequutils 命令降低 CPU 频率，具体方法是将调节器设置为ondemand。
