So I was at home, and I seen my blackberry didn't turn on. So I was thinking to my self. What's going on? I pushed the power button, and RED light followed by a 7 Green Blink-Code. I was what would that be? I tried resetting it. Didn't work. I found my own solution. Plug in the PlayBook and let it sit for 20 mins, then push the ➖▶️➕ Vol. up and down with the play button. While holding those three press the power button...wait till you see a red light (release). It will be dead. Let it charge.
