Now the computer won't turn on. I didn't trust the repair when they gave it back to me and it looks like my fears were valid. My only option is to make another Genius Bar appointment. I'm glad I had a horrid Windows laptop just to have SOMETHING to use during this continuing debacle. I think I'll probably buy a slightly better non-Apple laptop and put Linux on it. If you'd told me I'd even think of doing this a month and a half ago, i would have scoffed at you.
