My New Mac Book Pro has A hi pitch beep coming from the lower left side by the hard drive . It is not a hard drive sound not a clicking but a beep and the odd thing is launching photo booth stops it for good till restart. Then its starts beepin ever 45 sec to minute and also when you touch keys or the track pad . but never beeps after you launch photo booth . Anyone else with this beep or have an idea of what it could be . Apple offer to doa it and send me a new machine . But this screen is perfect so i hate to cahnce getting one with a bad screen
