Guest simonc Posted January 15, 2008 Posted January 15, 2008 I have a laptop set up with both Windows XP and Windows 98SE. When I use XP the fan briefly comes on at full power then settles to a low level. When I'm using 98SE the fan seems to be on at maximum power constantly, even when I'm not doing anything. Is there something in my setup of 98 that is sending incorrect messages to the fan control (the BIOS, presumably) or is this a well known issue with Windows 98? What could I try to solve this problem? Grateful for advice.
