My macbook pro has never made weird sounds. It is 2 and a half years old. It has been dropped twice, but not recently at all. Upper left side of macbook pro made very loud scratching sound as I opened it from sleep. It only did it when I had the laptop at a certain angle. It is still doing it. Im currently backing everything up to an external hard drive. I'm very worried. It was very loud, not the fan, not the usual disc slot movement, not the speakers. What should I do? PLEASE HELP. THANKS in advance! -Andras.
