MacBook Pro A1151 not booting up normally
The Macbook Pro in question does not always boot up properly. One of three things happen:
1) the MBP does the chime and then repeats the sound over and over again in a continuous cycle but never starts up.
2) It boots up to the apple logo and then flickers off until the entire screen goes dark. There is no video out signal to an external monitor as I attached one to the DVI port so I know its not finishing starting up. See this video I made: https://www.youtube.com/watch?v=Lvlqk7PG...
3) It starts up normally but goes dark after a couple of minutes.
I have reset the PRAM and SMC as well as tried booting from the DVD drive. None of those did anything to help
Is this a good question?
