Tried using a nail file to level the pins. Tried turning it on and off every few seconds or so. Tried using both the usb port charger and the Blackberry rapid charger. Must have done something right as it is now charging. The tablet belongs to a friend of my daughters and she is lost without it, so happy to get it going again for her. Will tell her not to let the battery get that low again. Thanks for all the awesome suggestions.
