Macbook laptop, $50. It is stuck on the loading up screen, and if you get a tiny screw driver to unscrew the cover holding the battery in, you just need to remove the battery and put it back in. The laptop will finish booting up! I had a hard time trying to get the screws out, bended the cover to the battery a little bit. Selling it for cheap, since I bent that and the battery still needs removed and put back in.
