@MRDManna,

Thank you for posting your query on HP Community,

Let's try re-installing the Microsoft ACPI-Compliant Control Method Battery and updating the Bios on your PC: 

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.

Thank you for replying, @MRDManna,

In this scenario, I would suggest here is to run a test on the battery either from HP Support Assistant or you can try to run the test on the battery from F2.

1. Hold the power button for at least five seconds to turn off the computer.

2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.

3. On the main menu, click Component Tests

Battery Test

HP PC Hardware Diagnostics (UEFI) tests the functioning of the battery and can calibrate the battery if needed. The Battery Check takes about two minutes and the calibration can take two hours or longer. Follow these steps to perform the Battery Test:

1. In the Component Tests menu, click Power, and then click Battery.

2. Click Run once. Figure : Battery Test - Run once

The Battery Test begins.

3. When the battery test is complete, the results are displayed on the screen. For additional battery information, click Battery Details. If the battery fails one of the tests, write down the failure ID (24-digit code) so you have it available when you contact HP Customer Support. The information is also available in Test Logs on the main menu

If the test passes, I would suggest here is to uninstall the battery drivers and then update the Bios. 

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, 

Restart the computer and the issue should be fixed. 

Also, Go through them all and let me know what you have determined is causing the issue. 

The first document has the most relevant troubleshooting if your battery appears to be not charging. 

Battery Does not Power Notebook or Hold a Charge 

If the test passes, I would suggest here is to update the Bios on your PC, HP Notebook System BIOS Update (Intel Processors)

Please let me know if this helps.
