Hello, I got an iBook in April 2006 right before they released the MacBook. About two years later, I saw something pushing the plastic outward off the screen, right about where it says 'iBook'. I stuck a fingernail in to try to get whatever it was out (oops) and my screen immediately went black. You can still make out whats on the screen, but just barely.. mostly where the light is coming through the Apple logo. I just recently took it to get fixed, and they are saying it's going to cost £500 to fix, because it's something with the logicboard. I'm not computer-savvy at all, but I'm not convinced I didn't cause some sort of damage that should be relatively cheap to fix. Can someone educate me on what might be the problem before I pay the £50 service charge just to get my broken computer back? Thank you!
