My G4 12" PowerBook hard drive is dying and needs to be replaced. I have some detailed instructions or a local Apple Authorized Repair Center that can do it for $100-$120. I have reasonable technical ability. (popping keyboard keys off doesn't sound like fun though). For those that have done this should I pay the money to have it done or give it a shot doing it myself??? (This laptop is my backup but I would like to not screw it up too badly) Thanks!
