I am trying to fix a Early 2011 MacBook Pro 13". I have tried to diagnose the computer and all that is happening is you turn the power on and it tries for almost less then a second to power up and then dies. I opened the computer up to see if anything was loose and nothing is. Iv'e been told that he was just using the computer and it just out of the blue stopped working. Would love some help to try and get this working again as I don't think I should give up as its not a very old machine. Thanks. James.
