My Envy13 runs on power cord only despite 79% battery

[MFPH]

I have an HP Envy x2 detachable 13. It stopped using the battery at all about a year ago. I thought it needed a new one so didn't bother as it runs fine plugged in. I investigated today and see that I have a perfectly fine battery with 79% juice and it is detected and passes the troubleshooter. However, my computer shuts off and won't turn back on the second the power cord is disconnected. Any ideas?

@MFPH Due to the current global COVID-19 situation, we're seeing an influx of customers coming in for support and we appreciate your patience.

That said, I have a few steps listed below that should help you resolve this concern:

Unplug the charge, Turn off the laptop and turn it back on after 30mins.

Reinstall Microsoft ACPI-Compliant Control Method Battery under device manager:

1) In the search box, type and open “Device Manager”.

2) Expand “Batteries”.

3) Right-click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there.

4) Click on “Uninstall”.

5) At the prompt put a check in the box to remove the current driver

6) Shutdown the computer.

7) Remove the battery for a minute and then put it back in. (Skip this step if you have a non removable battery)

8 - When the computer comes back up it should automatically find the driver.

9) Go to Device Manager.

10) Expand Batteries.

11) Right-click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there.

12) Click "Search automatically for updated driver software"

Do the same thing with Microsoft ACPI-Compliant Embedded Controller.
