Thank you for posting on the HP Support Community.
 

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

• Did this happen after a recent window or software update?
• Did you make any changes to the settings of your PC prior to the issue?

While you respond to that, let's try 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. (only for removable battery)
• 7. Hold down the power button for 1 minute.
• 8. Insert the battery only. (only for removable battery)
• 9. Attempt to turn the battery on.

Hope this helps! Keep me posted for further assistance.
