MacBook Pro screen goes dark

I've had my MacBook Pro for two years now; no problems so far (it has had 3rd party RAM from the get go).

"Take out the battery, and unplug it from the outlet. It could be that the machine has gotten into a bad state the SMU has become confused.

Once you remove the battery & external power, hold the on switch for 10-15 seconds...

Replace the battery and see if it turns on, and works properly...
If so, go ahead and plug the power cord back in..."
