i have applecare on my MBP. i've been problems with my backlight being uneven lately, so i was going to bring it in. then a few days ago, i'm getting out of my car and the strap on my bag broke, and the bag, with the computer in it, took a fall. there's now a dent - not horrible, but an obvious drop - on the bottom half of the case at a corner. it has had no effect on the computer's running at all - just a cosmetic thing. does this void applecare? if so, what would you do? i looked into replacement bottom cases, but they're $200 minimum and very difficult to install, or $300+ to have someone else fix. what do you think?
