Hi, I've got a Sony VAIO that I like to run Ubuntu on. When I run it off the mains the CPU stays pegged at 1.995GHz and the CPU fan sounds like a hoover. When running on the battery the CPU stays at a nice 786MHz (or whatever) and the fan is nice and quiet. Is there a way to switch the CPU speed to the lower speed when it is running on mains to protect my hearing?!
I've tried cpufreq-set etc without luck, although I may not have used them properly!
Any tips would be appreciated!
Thanks
Simon
