Does anybody know what this is?
My 13" MacBook Pro 2.5 ghz keeps doing this when I sometimes move the screen up or down and sometimes it does it randomly and then starts beeping and I hold the power button down and it restarts and is normal until it goes like that again, this is my third Mac because of this the other two were under 3 month return policy if anyone knows what this is please help! Thanks.
MacBook Pro (13-inch Mid 2012)
