Try using a very small amount (seriously a little is alot) of hand sanitizer or cotton q-tip dipped in rubbing alcohol to clean the ports of the charging cord, I did the USB port too. With the plug not connected to the wall, slip the charger into the tablet in and out to clean the tablet port with the small amount that is on it's end. Allow ends to completely dry before plugging into outlet. Because it is alcohol based it will dry quickly.
