Your PlayBook is likely fixable by yourself.
LEAVE it connected to the wall outlet charger (not the USB > PC charger).
Leave it connected for 24 hours... every 3-5 hours, press and hold the power button only for about 20 seconds. Eventually it will boot on up, but first must reach a certain charge level.
You will see the blinking red and perhaps yellowish LED light, and perhaps a symbol on screen of "no battery". That means the battery is drained, but it must reach a certain charge before powering on.
