Hello Biff and thank you very much for replying.  I use a rather old HP laptop. Mobile AMD Sepron processor 3500+, 1,58 GHZ, 896 MB Ram. I have searched fo additional drivers but all that was retreived is a driver for my wireless card.

Bumping this thread as I have the same problem with overheating. Being completely new to Linux I recently installed Watt OS R5 and I really like it. The big hurdle now is to overcome the overheating problem. (Or the fan problem) I have noticed that the fan speed is completely static when I use Watt OS. If I boot up the computer when cool then it will use a minimal speed which will not do once I watch a video on YouTube. At other times when I boot up the fan speed stays too high. Before posting here I did try the advise in the link below. http://www.webupd8.org/2011/06/linux-kernel-power-issue-fix.html Unfortunately nothing happens when I enter gksu gedit /etc/default/grub As both Jupiter and psensor is installed I think these should somehow enable automation of fan speed too. But I don’t know how. If anyone can point me to a solution please let me know. This post was edited by Prague, Oh Prague at April 8, 2012 6:46 AM PDT
