So a couple of days ago my macbook was sitting in its laptop carrier case and it fell. I didn't have time to check if anything was wrong so I simply went to class. In class and throughout the day my laptop was working perfectly fine. Except, when I moved it around and tilted it vertically there was this very distinct shuffling/rattling sound inside, as if multiple parts were loose. It sounded like there was loose change rattling around inside. So now, I am 100% sure that there are some loose pieces moving around my laptop. The thing is, this happened on Wednesday and my laptop has still been working fine. I was going to take it to bestbuy because I have warranty there but I am scared that they are going to take my laptop in for a couple of weeks to repair, and I don't have that time because finals are coming. I've backed everything up but what do you suggest? Should I take it in sometime next weekend or let it be since my laptop has not stopped working? Thanks!
