The period key on my 13" 2008 Unibody MacBook is coming off - it is loose and lifting away so that the underside is visible. It doesn't yet come away completely and still functions just fine. Should I take it in to an Apple store to get looked at, or will it be fine for a couple of weeks whilst I finish university for the year? I ask as I do not want to be at university without a computer. If I were to take my MacBook in for a repair - how long is it likely to be in for? I have 4 days before I go back to university and I realise that it is unlikely to be repaired in so short a time.
