After getting about a 20% charge as Owen mentioned if it still won't start, remove the battery and AC adapter then press and hold the power button for 5 seconds. Replace the battery and power supply and give it a try. Yes, this machine does have a PRAM battery. If you keep losing the date and time, you'll need to replace it.
