New Alum MacBook Waking from Sleep

[NewGuyToMac]

I bought a 2.0 Ghz MacBook about 2.5 weeks ago and havent had any problem until about 10 minutes ago. I was working on a document with Word and was finished working and closed the lid like I normally do. I went to open the lid to continue working, when I opened the lid, the screen came on real quick and then flashed off. I couldnt do anything, I closed the lid and tried to re-open it, and the screen turned black. I ended up having to hold the power button down for a couple seconds and turn it back on. Should I be worried about this or was it just a snag?

Thanks for the help!

You may want to try resetting the power management system.
1. Turn your MB off
2. Remove your battery
3. With your battery removed hold down the power button for 8 seconds
4. Place the battery back in and power up
