I know im a bit late with this, but i just got this tablet from a friend that passed away and left it to me. I could not get it to charge at all. I used the USB(did not work), then i used the DC(did not work)..so i got the stupid idea to use both(the USB cable and the DC cable )…Now it has the power to charge.
I probably should not do this, but i was at a loss.
Hopefully this will help for the peeps in the future, if they wind up getting one from someone else.
