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:
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.

Battery Power -1*
AC Power -1

What's the deal??

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.

Hey guys, I feel like such a bimbo for saying this but it happened because I was always frequently working with my Blackberry (sort of like a magnet, basically) on my laptop. After I stopped working with it near my phone it turned out fine.. sorry and thanks for your help anyway guys

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.
