My superdrive has a U shaped bend that is preventing a DVD from being put into the computer. I haven't put a dvd into the drive for about a week, and I have carried it on the road for a week, so I have no idea when the damage happened. I already talked it over with the Genus, he said it was from carrying my computer open and holding it in the middle (near the DVD drive.) He said if you carry the computer open you should hold the palm rest only. I'm getting the bottom case replaced, I have applecare but it doen't cover this kind of damage. The guy did cut me a break however, he is still charging me the $100 for a new bottom case, but is giving me the $80 labor for free. My question is has anyone else heard about this issue with how you carry the macbook? From now on I'm going to always close the lid before I carry it anywhere, but I was just curious if this was a common thing.
