For second time, i became 60% shut down.

Later, 80% shut down

Finally, unplugged = shut down.

Battery check = passed.

@sui3 Welcome to HP Community!

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

Unplug the charge and use the laptop until the battery drains to 15%.

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

Reinstalled 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 minute and then put it back in.

😎 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.

Restart the computer and the issue should be fixed.

If the issue persists, tap F10 to boot into the BIOS screen, and check if the PC shutsdown while you are in the BIOS, that should confirm if this is either a hardware or a software issue,

Also, check with an alternate adapter or another wall outlet to be on a safer side.

i have tried to uninstall that in the device manager, shut down, remove all peripheral devices, remove the battery for 1 minute, hold the power button for 1 minute, turn on, device manager scan for hardware changes for the battery, update the windows and the bios, restart....

still ain't working... the battery will continue with 96% (plugged in).
