Hi, I have a mid 2010 15" Pro, and yesterday the some keys on the keyboard have stopped working, more specifically the 5,6 and 7 keys. The machine is still under Applecare and will be till 2014. Although being hardly noticeable, the bottom of the optical drive also has a dent that has pushed the frame around the drive up. This does not affect any internal parts. I know the dent would not be covered, so do Apple replace the entire top housing or just the keyboard? I have upgraded friends pro's and the entire keyboard looks like a pain to take out. Any opinions would be great!
