I had a Macbook that was stuck in sleep mode but was working perfectly when connected to an external monitor but internal monitor stayed black. Finally the machine had a logic board issue.

Try removing the battery. I've seen near-dead batteries keep a machine in sleep mode and not let it wake up. After removing the battery and AC, connect the AC again, and immediately reset the PMU and PRAM.

Does the machine chime when you power it on? If it does, it may be a screen-related issue (check to see if there is a dark image on the screen), and if it doesn't, I would reseat the RAM and test for bad memory slots.

0. Connect AC adaptor, make sure it's plugged in

1. Check if screen brightness is not set to 0 - AFAIR it will be F1-F2 keys

2. Connect USB device like mouse/keyboard/pendrive - it can wake up

3. If 1&2 doesn't help - you can shut laptop down by pressing power key - then start it up and check Energy Saver settings

4. If it will stuck in sleep again consider resseting PMU, read Apple Support article - http://support.apple.com/kb/HT3964

5. If PMU reset won't help contact Apple - it can be kind of hardware problem

I had some success by simply turning the screen down to 0 by pressing F1, then repeatedly turning it back on (F2) and off (f1) a few times. At first the screen just flickers the goes black, but the more i repeated F1 then f2, the brighter the screen got and the longer it would stay on. Eventually i was able to dance between the buttons and get the screen up to full brightness. This isn't a solution, but it would indicate some kind of software issue is at the root of the problem.

Try connecting to an external monitor so you know it's not a video chip problem?

Press power button and keep it pressed for 5-10 seconds. This should cause it to shut down (a sort of force shut-down). Wait for a few minutes and then press it to start up in the usual way.
