I have Mandriva on a laptop. This is too slim on details for me to really point you to a solution. If it's Core Duo based and a current Mandriva read this link:
Now my suggestion here is to configure it to "ondemand".
I have just started to use Linux properly for the first time. I am currently dual booting Vista and Mandriva. Everything is going great apart from the fact that my computer is running much warmer and fan is very noisy in comparison to Windows Vista. However, I can't seem to find a simple to use GUI based program that will let me turn down my CPU frequency (or otherwise help me power manage). Can anyone help me cool down my laptop, as it turns off every few hour on Linux due to the heat.
Thanks in Advance
