It has a "smart" fan control, which regulates the speed of the system fan according to the temperature (a Thermal Zone in ACPI terms, yes?). The problem is: as soon as Linux gets control from GRUB, the fan goes to full speed and stays there. I have flashed the BIOS to the latest (which claimed to fix a fan speed problem with Windows), but the problem persists. So I don't know if it is a case of pilot error, a Linux bug, or a BIOS bug. Any help sorting this out would be much appreciated :) Please CC me on replies, as I'm not subscribed to acpi-devel. --Eric ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf
