I have a 12" Powerbook G4, the original model with VGA and everything. I know, it's kinda old. The hard drive died about two weeks ago, so I've been using my old iPod as a Firewire hard drive since then. I ordered a nice new hard drive from Newegg (a 5200RPM 40GB one with 8MB cache) and it came yesterday, and earlier today I went to CompUSA to have them install it for me. I would rather pay $30 to have someone trained in Apple hardware take apart those cursed beasts that are modern Apple laptops than try to do it myself and end up breaking or losing something.
I left the computer, the new hard drive, and the power adapter with the guy, and he told me to come back in an hour and a half. So I did. I paid for the repair and got the computer in my bag, then decided I should test it before I took it home, just in case. I opened it up and pressed the power button. Nothing happened. I tried again. Nothing happened. I checked to see if the battery was charged, and it was. I held the power button down for a few seconds, and tried a few more times. Nope..
So the computer is still at CompUSA, broken. They're supposed to call me tomorrow if they fix it. It bugs me that they messed it up, but I'm glad I paid them to do it so that they are liable if it can't be fixed.
