HP Pavillion Notebook battery will not fully charge

[ewl15]

The computer i have is 2 years old. This issue has been going on for most of the life of the computer (if not the whole life), but I never did much about it. The issue is that the battery would not charge more than 39%, I switched out the battery charger with friends and got the charge up to 100% once, but after that initial charge it never reached 100% again. I since bought a new charger and the max battery life will reach 55%, but go no further. This is progress from 39%, but what is the issue and why wont the battery fully charge? Anything I can do to repair this?

@ewl15 Welcome to HP Community!

I understand that the battery will not charge  100%.

Do not worry. I will try to fix the issue.

Please perform the battery test and check.

1. Power off the PC and make sure that it is completely powered off.

2. Press the power button and the moment you press the power button immediately start tapping F2 key, you should see the system diagnostics screen.

3. Look for the component test, under that all the hardware will be listed, please choose Battery and initiate the quick test.

Note: If it fails it will generate a 24 digits alphanumeric failure id, please capture that.

If the test is passed, perform the below steps.

Unplug the charge and use the laptop until the battery drains to 15%. 

Turn off the laptop and turn it back on after 30mins. 

Reinstalled Microsoft ACPI-Compliant Control Method Battery under device manager: 
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.  

😎 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.  

Restart the computer and the issue should be fixed. 
 

Also, please update the BIOS.
