I wonder if you switch event mode to poll mode, does this problem still remain?

cpupm enable event-mode
If I change the last line to:
cpupm enable event-mode
and run pmconfig the powertop output doesn't change change much
and the wall outlet power doesn't drop (220W idle). If I boot
Vista without changing any hardware or BIOS settings the idle
wall outlet power is 40W less (170W).
