will not take a charge when it is plugged to charger.

@lori1954 could be your charger, try a different one. If that still does not work, try a different cable. No luck with that, check the connector on your tablet. Make sure it is not bend, has broken pins or is full of lint/debris. Use a few puffs of air to clean it. Should that also not work, you are most likely having issues with either the battery, that actual charging post or some board issues. For that you will have to open your tablet and start replacing the battery. Then recheck.
