Just have to share this. I bought a MacBook in January. About a month ago I noticed a very small defect in the screen. I took the computer to the Genius Bar and a genius decided there was a tiny crack in the lcd unit. It was really quite small, just a short diagonal mark that was almost invisible, except that it was located near the center of my screen. I had been polite, and had simply asked for a diagnosis. The genius told me that the policy is not to repair very minor defects in lcds. But then he noted the excellent condition of my machine, and said that if this were his computer he'd want that lcd fixed. So he authorized a complete lcd replacement, all under warranty! But it gets even better. He told me that they were currently backlogged, and that if I left the machine for repairs then it might take 5-7 days. He suggested that I wait a week, and they would order the new lcd and give me a call. Well, one week later I got the call, and I dropped off my computer yesterday at 10 am. I was asked at that time if I understood that the work might still take 3-5 days. I got a call today at 11 am, saying that the repair was done. Not only is my screen free of defects, but the quality of this new lcd seems even better than my old one. Brighter, with more even backlighting. Way to go. Hats off to the Lehigh Valley Apple Store!
