@Denizen,

 

Thank you for posting your query on HP Community,

 

Let's try re-installing the Microsoft ACPI-Compliant Control Method Battery 

 

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. 
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. 

 

Also, try updating the computer - 

 

Step 1 Windows Updates - 

1) In the search box, type and open Windows Updates. 
2) Check for updates. 
3) If the updates are available, click on install and restart the computer. 

 

Step 2 HP Support Assistant Updates - 

1) In the search box, type and open HP Support Assistant. 
2) Check for updates. 
3) If the updates are available, click on install and restart the computer. 


Hope this helps! Keep me posted.

I had to repeat the process two more times before it worked.

 

The rear cover was unexpectedly difficult to remove and there was one hidden screw behind a rear rubber footing strip.

 

The battery display now reports plugged in and charging and 39%. I won't be satisfied until I see charge go to 100%.

Hi! @Denizen,

 

Thanks for the update.

 

Please try the steps recommended below and check if it helps.


Check the BIOS to confirm the setting is set to Full Charge, if it is not, change the BIOS setting to Full Charge.

 

Power on the unit.
Press F10 to enter the BIOS.
Select the Power option. 

Full Charge: The battery charge stops at 91~100%. 
Extended Life of Battery Pack: The battery charge stops at 76~80%. 
Optimize Life of Battery Pack: The battery charge stops at 46~50%. 

Save changes and exit the BIOS.

 

Also, try the steps recommended below.

 

Remove the AC adapter and discharge battery capacity to 10 percent or lower.
Re-connect the AC adapter and check if the battery can be charged to 95 to 100 percent (95 to 100% is normal).
If upgrading to F.45 does not fix the issue, replace the battery.
If replacing the battery does not resolve the issue, follow the standard repair process to get the issue resolved.

 

Run Power Troubleshooter.

On Cortana, enter  Troubleshooter then select Troubleshooting.
Click Improve power usage to open the window, then click Next. 
This should run the troubleshooter and can fix any detected issues. You may try restarting your computer and charge your battery again.

 

Let me know if this helps!

Happy Weekend ahead! 🙂
