Hi, I am in the process of replacing the hard drive in my Powerbook G4 and have run into a problem. One of the three phillips screws inside the battery compartment would not come loose, and is more or less stripped. I am wondering what the best step would be for me to take? Since it's just a very small screw, I'm hoping I can get it out manually, and not have to drill or take any action along those lines. Suggestions?
