Less likely - but takes just a tiny bit of time to implement...

Method – Reload the Driver


Symptoms:  Battery stops charging – no known issues with battery or charger – Windows 7 through 10


Control Panel > icon view > Device Manager > Open Batteries > Right-ClickMicrosoft ACPI-Compliant Control Method Battery" > Uninstall > tab Action > Check for hardware changes (re-installs the driver)




Could be that the battery actually needs to be replaced.  Please test.


Battery seems “stuck” in a particular charge setting   

The battery might be OK and just need calibration (balance / set).
