I just got a call at work from my stressed-out boyfriend - he accidentally knocked my laptop (15" Powerbook) off the coffeetable where I had been working early this morning (and I had foolishly not put the computer back in the case). Amazingly he said there is a lot of damage to the back left corner - major impact dent; power cord won't plug in; he says it's pretty messed up. From reading archived posts, it looks like it's going to be a pretty expensive repair. I have no idea if the hard drive (superdrive) and everything else is working. A friend suggested buying a replacement case; are there any diagnostics I can do myself? Should I bring it in to have it assessed from an authorized service place first, just to know? Thanks for any advice!
