So a friend just gave me his Macbook Air 1,1 on which he spilt some water. He wiped it away immediately, turned it off and upside down but alas the "l" key is no longer functional. However all the others are.
PRAM reset, no luck. Lifted keycap off, nothing unusual visible but still doesn't work. I'm going to leave it off and evaporating for a little while to see if that changes anything, but any suggestions would be great.
Incidentally, he also is still covered under Applecare. Can we get away with a repair on this? There's no water damage marker is there?
