There we go a mere 5.9 watts at idle, 20 under crusing.

 

Interesting. I significantly undervolt the CPU in this laptop. I run it so
that it doesn't go over 2GHz [C2D T7400] which was 1.2125V factory spec but
I have stable at 0.9750V. (Full speed, 2.13GHz, requires 1.0125V [down from
1.3425V] to be stable. However it runs significantly hotter at that but only
marginally 'faster'.)

The benefit is that the fan doesn't come on very often and the battery life
is extended by ~30%. It would be more but this laptop uses an IPS screen -
about the most power-hungry type.

I see in that article he intends to use it with an IPS screen but I dare say
his is LED backlit where as mine isn't. :-/
