You're running acpi now. Does the fan work? If so, you're done. If not, edit /boot/grub/grub.conf (make a backup copy first). Find the line or lines that start with 'kernel' and add "acpi=off" (without the quotes) to the end of those lines. Reboot. Now you will be running apm. If the fan works, then apm is probably what you want. If the fan still doesn't work, I don't know what to suggest. By the way, I learned all this by searching and reading the list archives. It's fun--I recommend it. Find a link at the end of every list message, or go to http://marc.theaimsgroup.com/?l=fedora-list&r=1&w=2 where some good people maintain another archive (with a more reliable searching tool) of the list. good luck, Matt
