Strange, a Core2Duo-Thinkpad should consume above 8W when idle (HD & Backlight off). Plus around 30-40% on the AC side due to bad low-power efficiency of the power supply.<http://dict.leo.org/ende?lp=ende&p=eL4jU.&search=effectiveness> > Might it be that the powermeter gets confused after a while because of the > harmonics of the frequencies ?
