I just installed a Mountain Lion update and as it was finishing, I heard the computer make a short beeping sound and then the screen went black. I tried pressing some keys but the screen remained black, despite the power light and fan remaining on. After pressing and holding the power button, the fan and power turned off. The computer will not turn on now.

 

What's going on with it??


MacBook Pro (13-inch Mid 2010), OS X Mountain Lion (10.8)
