    Ok, calm down calm down.

     

    Does it come up with any message before it shutsdown? Or does it just lose power all of a sudden?

    Ok.

     

    First of all, if you have anything pluggged into your macbook, unplug the lot. HDD's, mouse, keyboard, whatever. Except the power cable I guess. That can stay.

     

    If that doesn't solve the problem, then it's not one of those items causing it. And in that case, continue:

     

    Open Terminal & run the following command, posting the results back here:

     

    pmset -g

     

    Load your Snow Leopard Install DVD & hold C while booting & go to Utilities > Disk Utilities. And repair disk & repair permissions.

     

    Could you also run the Apple Hardware Test by loading your Applications Install DVD & rebooting while holding D.

     

    Then could you boot up normally & have a look in Console, and do a search for shutdown. Post any results.

     

    Start with that beginning at the top.

     

    And stay calm. Your data is still on your HDD for now.

    I have my macbook late 2007, battery removed because I broke the button. My screen has been going black this week although I've been using it with the open bottom for about 2 months. Nothing magnetic because I always use it on a lap desk. The desk is hardbodied with a cloth overlay, no metal. I did a diagnostic with my original disk and it found nothing wrong. I've gone to a black screen sleep mode about 5 times this week and it also went to a complete shutdown once. Any ideas for me.

    This sounds great but I can't get mine to come up to even start this process.

    maninder288 solved my problem. I was working without my battery in place because the button that holds the door on was broken. Although I used it on a laptop desk, it must have picked up some magnetism. As soon as I taped the door in place it worked fine and has worked for months since Oct of 2012.
