Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I hope I can help one way or other with the problem, which sounds severe and must be quite sobering.Is the charger the type that plugs into the tablet, or the type where the battery is removed to put into the charger?
If it is the type that plugs into the tablet, try powering On the tablet with the charger connected - does it power up normally and operate OK that way?
