Hello all, I sent my 2.5-year-old Macbook Pro to Apple for a keyboard replacement, since the right arrow key stopped working. When I got it back, Apple had replaced the following parts: Top case and keyboard Flex Cable/Audio Logic Board (item 630-7983) Logic Board (item 630-7709) 2 GB RAM The cable and two "logic board" items were marked as replaced due to an audio issue. I don't know of any audio issues or RAM issues with the computer before it was sent. So did they find some tiny issue I hadn't noticed, or did some Apple repair tech just need practice with a pre-unibody Macbook Pro? Oh, and of course, when the computer came back, the new keyboard had its own issue, with a flaky period key. So I had to send it back again. Though the second try seems flawless so far.
