My device wont turn on and not charging. The batteries appear and disappear all the time. I tried everything without any results. The problems seems to be the big consumption of battery at the startup. The battery work fine.
My solution was: i remove the back of my tablet, i disconect all the sockets and put the charger on it for 10 minutes. Then i connect just the socket near the middle of the tabket between battery and metalic protection, and wait. After few seconds the battery apear and the charger works. I wait about 5 minutes and after that i connect the rest of the sockets disconected. All of that was doing with the charger connected. After the battery was 100% i put on the back of my tablet and press the power button. It work ok without any problems. In the future never let the battery to reach at 5%. Godluck to all!!?
