Comment 17 for bug 132271

I may have an explanation for my cpufreq problem. I read that a dying CMOS battery could cause such problems. My CMOS battery is low, indeed : I got a message on boot about this some time ago. However, I have a laptop (Fujitsu-siemens Amilo M 6453g) and I couldn't find the CMOS battery : so I can't change it... Anyway, for some reason kernel 2.6.20 still manages to adapt my cpu speed (although 2.6.22 and Windows XP can't anymore). It would be iinteresting to know why 2.6.20 is less "sensitive" and maybe try to get this behaviour back in recent kernel.

My laptop is only one year old and the CMOS battery is already dead. Plus, I opened the laptop and I couldn't find it... Maybe there is no way to change it... I contacted user support from the website and I got no answer.
