Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• Did this happen after a recent window or software update?
• Does the notebook shut down immediately (right after you unplug the charger)?

While you respond to that, let's try these steps: 

Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8. (do not skip any troubleshooting steps even if you feel steps are repeating)

BIOS default:

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer. If the issue persists, follow next steps.

If the test passes, continue with these steps:

1. Go to Start, search for Device Manager, and open this result.

2. Expand batteries.

3. Right-click on the ACPI option (usually the 2nd option) and select delete or uninstall. Follow the prompts.

4. Shut down the computer. 

5. Disconnect the charger.

6. Remove the battery.

7. Hold down the power button for 1 minute.

8. Insert the battery only.

9. Attempt to turn the battery on.

Hope this helps! Keep me posted for further assistance.
