I just got an hpz3000 with a pm at 1.6ghz, when running on battery it is showing a clock speed of anywhere from 221mhz to 598mhz, and when plugged in it is showing 595 (regardless of power settings), this is from systemproperties in xp, havent tried with saundra yet. Are those speeds correct, as they seem awfully low (especially when plugged in) or is xp reporting the wrong numbers (maybe missing a ghz)?
