Laptop will not boot on battery

[Dionicio3]

Today I noticed that my laptop would not power on at all without being connected to the charger. In addition, as soon as I remove the charger, the laptop shuts off immediately. Both Windows 10 and the BIOS diagnostic tools report the battery being at 100%, even after letting it discharge for a while. BIOS settings aren't being erased so I know the battery is outputting some power. I also disassembled my laptop and everything looked and smelt fine (no burning smell). I'm not sure if this would require me replacing the battery, or if there's anything else I can do instead.

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 😊

This unfortunately didn't help, after reinstalling the drivers and updating the BIOS, the laptop still immediately shuts down when the charger is removed. I'm thinking it's probably the battery which sucks as that doesn't look like the cheapest thing ever.

I am unable to run any tests on the battery as they all cancel due to the charger being plugged in. But if I unplug the charger, the laptop immediately shuts off and is unable to turn back on
