How to fix a laptop that turns off with a critical battery warning that comes on

Hello, how can I fix a laptop that turns off with a critical battery warning while using the adapter, not the battery? All adapter connections are in good, so the battery should not be an issue, because I'm not using the battery.

Take the battery out, and it should run fine. Plan on buying a new battery if you fel you will need one.
