How's it going so it sounds like it could be a loose connection inside of it that could be a case of why it's shorting out on you I also had a tablet before and it would be so kind of the same thing to me as well and I plug it in and charge it but it wouldn't really charge it was just showing that it was charging and I found out that the charger that I was using wasn't strong enough for the tablet so that might be an issue as well if you guys are good at disassembling Electronics try taking it apart and as you take apart check to see if wire's are loose or if there's breakage in soldering from the board if there's solder breakage from The Wire then it's easy to solder it back together and you got to remember the pieces as you take apart where they go so they all fit back into it and that might work as well if problem still occurs I'll be happy to read more things to see if I can find out another solution for you please let me know and I'll always there to help
