Thank you so much Ed, and wouldn't you think that the Apple Genius guys would have already known this and not be thrown by why their 21" iMac would not charge? None of them had a clue and only by searching the internet did they discover there was such a problem. By then they had already done the electronic entries to give me a new one and it couldn't be changed. I can't believe I was the first one to bring this to their attention in the Louisville store?
