If you mean the hard drive, just pull it out and don't sell it. You can get enclosures fairly cheaply for 2.5" laptop drives which can access by USB on any other computer.
a few years ago, i bought a used alienware m17x laptop that supposedly has some pretty nice hardware. the laptop currently has a list of problems including the fact that it doesnt power on. I am trying to sell the laptop for parts and am wondering how i can extract the info containing this information. can you look this up through a number on the back?
