I have my 17" MBP besides me when it pronted me to restart after a software update. I am working in my other mac pro. Then I see the MBP with the blue screen for a while with no sign of activity. I press the power button, goes black and that is it. It won't want to start up again. The hard drive tries to read or something inside moves just once and that is it. Is not the hard drive broken, there is not reason and is not the sound of a broken drive, it sounds like the optical drive too. But the thing is that there is not activity, no sound of any sort. I disconected the batery, unpluged the machine, power up, reconect the batery and power and nothing. Is dead. The power light is on. It seems the software update did something to the computer. It has been on my desk for a week with Skype and messenger mostly. Any sugestion before take it to the Apple store?
