In trying to look for an obscure screw online (I think a stainless #6, 1/4", beveled Phillips head; I need it to replace the one I stripped at the bottom of my shower door), I came across a page detailing all of the different types of screw heads. I though Phillips was Phillips. Wrong, apparently. There are a ton of variations, along with some exotic ones that I've never seen or heard of.
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)..
