Press and hold the power button for 5-10 seconds, until the light goes out. Then press it again to restart your Mac.

It failed to wake from sleep or didn't completely shut down. Holding the power button forces it to shut down completely.

Ouch, I thought all Mac Users know this, that's why I suggested SMC reset, good it is solved.

Macs do have sleeping problems once in a while, I have a new Mac Mini and it failed wake from sleep 3 times in a week, I set the sleep timer to never and it is solved for now, put to sleep manually.
There seems to be a bug in 10.8.2 and lots of people have this problem.

Yeah 10.8.2 seems to have wake bug.
Sometimes it just wont wake up and needs force restart.

And tbh, I did thought all Mac users knew how to force shutdown a computer...

How can we know this, if you do not tell us the model# or the generation of the MBP!?

If it is a model from 2007, 2008 or 2009, then it is possible, that your model has a defective NVIDIA GPU. I had a defective GPU in my Mid-2009 17" MBP.

In that case, a professional repair shop can help.
