Fedora 11 running very HOT on thinkpad X61s


Hi all,

I realize that my computer is getting very hot whenever I run Fedora. Any insight out there? Any help would be greatly appreciated.

thanks, Rasaan

Hi, first check if any process is using 100% (or less, but constantly) of your cpu ('top' command in a terminal is good for this). Then check that cpu frequency scaling is enabled in the BIOS and in Fedora. Last, check your computer for dust : it prevents the airflow and thus reducing greatly thecooling potential of your fans.

Thanks for the response. This is the output from the top command. I figured it had to do with CPU. How do I proceed with the BIOS step?

thanks,
Rasaan

BIOS setup? Your problem is that gnome-panel is running amok. Try removing applets from it one at a time and watching top to see which one was causing the high CPU usage.

Appreciate the input. How do I see a listing of gnome panel applets?

There's surely a way, but why not just right-click on and remove them one at a time? gnome-panel is the bar on top/bottom of your screen. Start with anything that updates.

try to check if you have the latest firmware for your BIOS laptop, sometimes there are issues with these laptops, that are solved with a firmware upgrade(thermal problems, IRQ freezes, etc.)
