I may be posting in the wrong place, sorry if that's so. Is anyone having problems charging your tablets? I have 2 for my kids, bought them at the same time, and we are having the hardest time getting them to charge at all. We plug the power cords into the tablets, the little red/green lights no longer come on. Occasionally the battery indicator on the screen itself will show totally green as if fully charged, when in fact the tablet battery was just dead. As soon as the power cord is disconnected, it gives the "powering down" message, due to dead battery. We've tried adjusting the position of the cords, thinking a loose connection, but still no luck. Both kids are fairly responsible and take very good care of the tablets, just seems odd that they should both have the same problem at the same time. New to the tablet world here, and any help would be greatly appreciated.
