Tried starting in the morning after power drained, plugged in, everything came back for a few seconds then the screen went black. Can't restart. If I hold powe button down 10 sec machine emits an intermittent beep which continues until I push power button again. Any ideas on how to fix?

Unplug all except the power charger. – Ruskes Sep 20 '13 at 8:11

1Does the pattern of beeps match one of the descriptions in this Apple document about "startup tones"? – Ashley Sep 20 '13 at 12:57
It sounds like your system is stuck in the completely empty battery mode (warning tone).
Try holding the cmd+r after you pushed the power button.

To completely reset it, remove power and disconnect the battery, then reinstall.
