Apple store does NOT check your computer after it has been repaired. So, when my computer came back from a new HD and a new Logic board, they handed it over. It was still broken.

Luckily, the nearest apple store is about 10 mins from me. I've talked to them about this too. My advice; If it happens again, and the handling of the situation is not to your liking, do not hesitate to get in to contact with Apple Corporate.
