Microsoft says that the above is the relative proportion of power sucked up on the typical Windows laptop. I think I would have guessed that the panel uses the most (I wonder how much LED backlighting changes this?), but I wouldn't have guessed the chipset would use more than twice what the CPU uses. Perhaps this is due to the SpeedStep (Intel)/PowerNow (AMD) CPU throttling? I also would definitely not guessed that the chipset sucks up 4x the power of the hard drive (I might have put that 2nd or 3rd when guessing)..
