What do you expect for us to tell you? If it's going to take that long, either a) they don't stock the part, or b) they have other repairs that will be done before yours. The time for the repair itself is irrelevant.I am having this problem with my Macbook as well, Apple said they will replace it, but it it will take 3-5 business days. This is pathetic, I can see that if I were to be the one doing the repair, it would only take me about 30 minutes and that's because I don't know exactly where the connectors are and have to be more careful than they do.
Really, it's a simple fix that should be able to be repaired while in the store.
