Welcome to the BlackBerry Support Community Forums.
If you're receiving the flashing green LED light, it sounds like the BlackBerry PlayBook battery is completely drained. I suggest plugged the BlackBerry PlayBook into the wall charger for several hours to get a charge again.
Let me know if the issue still persists after charging it after several hours.
