my battery is stuck at 72% when i unplug power the compuer shuts down

[gwambui]

a few days ago, I noticed that my laptop shut down when I unplugged the power source. the battery has been showing 72% no increase but slight decrease from 75 since I first noticed the issue. A few months back I had a slightly similar but less scary problem, the battery only charged upto 75% and with time this max went down to 62. A bios update and everything was back to normal. However, this time none of my old tricks seem to work. This computer does not have a removable battery so my @home options are limited.

Welcome to HP Community

I have gone through your Post and would like to help

Please reinstall the Microsoft ACPI Compliant Control Method Battery and check if that helps

Step 01. Click on the Start Button
Step 02. Type "Device Manager" in the start search box & open the Device Manager
Step 03. Look for Batteries and expand it by click on the + symbol on the left
Step 04. Right Click on "Microsoft ACPI Compliant Control Method Battery" & uninstall
Note: This Battery driver will get re-installed automatically when you restart the Notebook again
Step 05. Please Shutdown the Notebook
Step 06. Remove the Battery and unplug the Power Adapter ( For Notebooks with Removable Batteries )
Step 07. Press and Hold the Power Button for full 1 Minute
Step 08. Go ahead and put back the Battery and connect the Power Adapter and restart

Next update the BIOS from this Link: https://support.hp.com/us-en/drivers

If the issue persists run a Battery Test again to confirm the Hardware Functionality

- Hold the power button for at least five seconds to turn off the computer.
- Turn on the computer and immediately press Esc repeatedly, about once every second. 
- When the menu appears, press the F2 key.
- On the main menu, click Component Tests and Power > Battery

Let me know how it goes 😊
