well, it's been a while since you posted but hopefully you come here often. anyways, just unplug those two wires(don't worry I have the exact same powerbook) and unscrew the four screws on the back of the powerbook. These screws are located in the little compartment where all the expansion slots are. You will need a torx 8 screw driver to do this. Now put all the screws back and put the computer back together. voila! you have a new desktop computer.
