Hi Guys, Early today I put my macbook into sleep (Clamshell mode) and went out for dinner, when I came back home I pressed a button from my wireless keyboard to wake it up as usual. I heard the superdrive's active noise and saw the signal white light was lighten up. However the external display was totally black and couldn't be waken up so as a result I need to reboot my macbook by pressing the power button due to two black screens. After reboot my macbook I was confused, the wireless keyboard is not working and where the hell is my bluetooth icon?! It's completely disappeared on the manu bar, even in the system preference! I checked the bluetooth manu in system profiler and it said "no information"..I mean what the Fxxx?! Does anyone has the same issue?
