When I plug my tablet in both with its own charger and my USB it says charging but when I try turning it on I get a yellow triangle with an exclamation point over the battery at first it was stuck on the start screen and would not g anywhere after rebooting it now it will not turn on even with charger plugged in
@lgu97701 sounds like you either have a bad battery or a bad charging port/charger. Check the voltage on the charger. If that works I would consider replacing the battery and while you are doing that inspect the charging port to ensure it does not have any broken pins etc., and is still properly connected.
