Reset did not work, either the cable or charge port may be damaged. Look in the charge port and blow/pick out(carefully) any dust/debri that may be causing an issue. Try a different compatible charger/cord to see if that is the issue. If different compatible charger/cord does not fix, it is probably a damaged/loose port that will have to be repaired/replaced. If port looks/test good the battery or connection is probably bad. If port is found to be bad, this is really not a repair for the inexperienced because the charge port for your device is soldered to the mother board and the heat generated could cause further damage if not very careful. I will post a link to a tear down guide to get you inside the tablet to check the charge port and will also post a link showing what is involved in repairing a mini USB attached to the board. The last link is to new charge port, which you can also do a search for better pricing perhaps if needed. If not wanting to do the repair yourself have a good computer/cell phone repair shop have a look and estimate repair. Good luck.
