millerm09 , A lot of forums feel a factory reset can fix this type of issue, read and follow the steps in the first link below if you would like to try, all data not backed up will be lost.
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.
