I bought some extra RAM for my iBook and tried to install it, but was missing the right screwdriver. Once I had got the screwdriver and finally taken off all the screws I installed the RAM only to find that it didn't work. I ordered some a new stick but during this time my combo drive went. I went into apple to the genius bar and they took it away for a month or so. I got my new RAM but when I got my iBook back they tightened up the screws so much that I can't get into it to install the new RAM? Do you think that if I go back into see a mac genius that they'd be able to help me undo the screws and put the new RAM in? I don't want to ruin the screw threads.
