I had this issue with Windows 10 and HP Pavilion. I read several posts and tried them all for hours. I finally got it to work like this; which is similar to some posts:

1. Bring up device manager and uninstall the ACPI-Compliant Control Method Battery drive under battery
2. Shut down PC.
3. Remove battery and disconnect AC.
4. Hold power switch down for 60 seconds.
5. Connect battery (no AC yet) and power on. PC now running on battery.
6. Connect AC. It started charging! Note: connecting battery BEFORE AC seemed to do the trick.
