I've just noticed that there's a red light coming out of my earphone socket. Is this normal? Anyway to turn this off?
Most people fix it by poking around with a toothpick. Nothing metal though, and don't force anything to budge if they don't want to.
My sister's white MB had this problem, too (red light). It only came about whenever she used BootCamp. The rest of the time, it was fine.
