Problem with PowerBook G4, won't turn on

Hello,
I have a PowerBook G4, and since last night, it won't turn on anymore. In fact, I didn't turn it off; it was in sleep mode, and when I tried to use it, no keys worked to wake my Mac up, the screen is black.
The sleep light is still on.
Is there a reset button? (other than the forced restart that doesn't work.)
What should I do?
Thank you very much for your help.

    Precision,
    The real trick to reset the PRAM at startup is to simultaneously press and hold the following 4 keys upon startup:
    Alt - Apple - P - R

    Best regards

    Hello Alex,
    disable your battery and try to restart by holding down the Command (Apple) key and R at the same time to clear the memories. Restart again by holding down the Shift key, keep this key pressed until you hear the small sound at startup and until you see the word "safe boot" in the progress bar.
    Good luck!
