My MacBook Pro is a couple years old and has been a great computer until yesterday! I used it for an hour or so, left for lunch and came back to a machine that was off and wouldn't even turn on. When I push the button to turn on the computer the white light (on the button you push to open the clam shell) will come on for a couple seconds and you can hear a humming noise as though it is going to work but then there is a single beep and it quits. The computer never comes on, the screen doesn't light up, etc. Any ideas? I have the AppleCare Protection plan so I called Apple and they said take it to Best Buy which I did immediately. Best Buy says they can't do anything for it because it is a Mac so now a local (somewhat local, 45 minutes away) computer repair company will look at it tonight. Anyone else have this problem or any idea as to what is wrong with it? Thanks in advance for any responses!

    Welcome to Apple Discussions!

    Here is an article that may be of help:


    Possibly one of the resets would help.

    Also, the beep may be an indication that you have a RAM problem:


    Try reseating your RAM and see if this helps. If you have replaced your RAM with third party RAM, then try the original Apple RAM if reseating doesn't work.

    Good luck!

    Hi I am having the EXACT same problem with my MacBook Pro. I assume you have yours fixed by now? I would greatly appreciate it if you could share what turned out to be the problem and the solution. Thanks!!

    I had a humming problem with my Apple Mac Pro 8 Core desktop and it would crash at times, or it would show a blank screen at start-up sometimes. Good thing I do have Applecare until 4/2011 I did a process of elimination and figured it was my video card. Apple sent me out a new one and sure enough the humming stopped, no more blank screens or crashing. Hope that helps.
