Not your problem, though - it looks like the temperatur= e is reported in Kelvin and the code converting from Kelvin to degrees C turns out to be buggy. > I didn't get any information about thermal interface in > "Documentation/ABI/testing/sysfs-platform-asus-wmi".

Yes, this is a thermal sensor= =2E What is it you want to do (in addition to having it report reasonable temperatures) ?
