Pavilion Battery only charges to 64%

Microsoft Windows 10 (64-bit)

Only charging to 60%. Battery test is fine. What next? How do I calibrate the battery if I can't get it to charge to 100%?

Hi! @TimeWaste2,


Please share the product number of the PC to assist you better.


Have you tried charging your laptop using a different adapter?


Were there any recent windows update on the PC?


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


On your keyboard, press the Windows logo key and X at the same time to open the quick-access menu.

Click Device Manager.

In Batteries section, right-click on your battery driver, commonly it’s Microsoft  ACPI-Compliant Control Method Battery. Then click Uninstall device.

Restart the PC the drivers would automatically install again.

Check the BIOS (F.34 and later) 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.


If the above steps do not fix the issue, upgrade the BIOS to the latest version using HP support assistant.

Also, try the steps recommended below.


Run Power Troubleshooter.

On Cortana, enter  Troubleshooter then select Troubleshooting.
