I've been running 4.8 and OS/2 on this machine before, always docked, and temperature was never an issue. It's possible that ACPI in 5.1 does this - after all it has some kind of thermal support, but I have tried to disable this and it makes no difference. Just to be on the safe side, would the following line in device.hints be correct for disabling the thermal part of acpi? debug.acpi.disable="thermal" I think it would be, because replacing "thermal" with "children" made my system refuse to boot. No HW was detected ;) /Eirik
