For some reason, recently, one of the keys on my MacBook Air keyboard (Specifically, the 'h' key), is quite loose. It makes a terrible sound when I type on it and I subconsciously feel that it will fall off. I've looked online and it seems like I will have to pay Apple ~$250-300 to repair it, but my MacBook Air is under warranty (Bought it in the mid of April). Do you guys think they will repair it for me? Thanks in advance.
