The maximum load I saw was 40W (during the boot sequence - when
everything turns on at once). In normal running it hovers somewhere
below that.

I didn't check specifically. My laptop has a very dim LCD with poor
saturation and a horribly narrow viewing angle. No matter how you
position your head, 50% of the display is always inverted...

Should be noted: It's an *ancient* laptop!
(Now *my* laptop seems to do all this in hardware, not software. Doesn't
matter what software is running, the fan turns on and off now and then...)
