Notebook computer energy consumption [RE-wrenches]

I've measured two laptops - a Toshiba Satelite, and a Dell Latitude. I've
gotten both of them down to 15 watts on the AC side by removing all
unnecessary accessories, including the battery (built-in charger draws extra
watts with battery installed, even when fully charged), and putting them
into low-power mode. The measurement was made when the LCD back light and
hard drive was off. Both of them can draw up to about 40 watts under normal
conditions otherwise.

Toshiba 320CDT uses about 35 watts through straight Dc adapter which steps
voltage up DC-DC.
