My Macbook Pro (Late 2011, 15", 2.2 GHz) Keeps making a weird low short noise, Almost a beep. It does this while running, no disc in the SuperDrive.
My MacBook Pro keeps making a weird noise whenever running. It will make this about every 5-10 minutes. It's a very low, soft beep. Anyone else having this, or is something wrong with the MacBook?
MacBook Pro (15-inch Late 2011), Mac OS X (10.7.3)
