9。04 笔记本cpu只能工作在最低频率下

上面说的可以在800 MHz - 1.73 GHz的频率下运行，但是再下面又说 current policy: frequency should be within 800 MHz and 800 MHz.
真是搞不懂，怎么解决呢？

这工具靠谱么

true

用系统带的CPU频率查看只能定在800MHz，不管选哪个频率或模式都不变，BIOS已经把频率可调模式打开

查看下 cpu 工作模式，ondemand or conservative without ac-adapter?
如果是 performance 模式，应该始终是最高频率。

做梦呢?

[godzwl]

莫名其妙有可以了，真是郁闷

[godzwl]

重启后又不行了，cpu模式是ondemand，但是选择performance cpu也只能工作在最低频率上

我用的是wubi安装的，难道是这个原因？
