So I just got a notebook off of ebay that won't boot and I'm tying to troubleshoot it. It has power and everything. However when I took it apart I noticed that the Athlon cpu is nicked at the edges right where you push at it with a screwdriver to get it to "unlock". This is one of the models where the die is mounted on a pcb-like board that in turn mounts the pins and interfaces with the motherboard. Does the edges of that green board actually contain any circuitry which may have been damaged? I'll try to post a picture later if I can.
