Laptop battery not charging to 100%

[Praveen_99]

Hello community members,

I have kept my Pavilion aside for few months and the battery got completely discharged. When I started using it back again, the charging is getting stopped anywhere between 80% to 90%. As it is a sealed battery, I cannot remove it and try calibrating it. I uninstalled the 'Microsoft ACPI-Compliant Control Method Battery' multiple times without any use. I even discharged it completely (until it automatically shut down after running out of battery) and tried charging it. It still charges only up to 87%. Please help me get this resolved. Thanks in advance!

Hi@Praveen_99, Welcome to the HP Support Community!

I understand that you have a HP Pavillion X360 14  and the battery charges to 100% and then stops. You've done a remarkable job performing the steps. 

Did any software changes or updates happen on your laptop after which the battery stopped charging at 86%?

While you respond to that, I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

NOTE: You may skip any steps that have been performed by you already.

• Power off the laptop.
• Remove the battery out. If the battery is integrated and does not have a latch to release it then leave the battery inside the laptop.
• Disconnected AC adapter from the laptop.
• Press and hold the power button for 15 seconds.
• Reconnect the battery and plug the AC adapter.
• Power ON the laptop.

Now let us uninstall the battery drivers and reinstall them. The following steps will help:

• Open the device manager. 
• Expand "Batteries". Right click on the ACPI battery drivers and select uninstall. If there are multiple entries of the ACPI battery drivers then uninstall them all.
• Close the device manager.Restart the laptop.
• The Windows operating system will reinstall the battery drivers while restarting. 

It is a good idea to download and run a BIOS update for your laptop via this link. The charger must be connected until the BIOS update is complete to avoid any power interruptions due to battery draining out. 

Post a successful BIOS update,  you may check if the battery charges fully. If not then please perform the steps as described in detail in this HP document. These steps help in testing and calibrating the battery. 

NOTE: Please skip the steps mentioned in "Test and calibrate the battery using HP Support Assistant".

I sincerely hope this fixes the issue. Keep me posted.
