System Board (00A)

My laptop also does not recognize my power cord. 
However, when I turn it off and leave it plugged in, the battery is full when I turn it back on after a few hours. 
But when the laptop is on and plugged in, it looks as if it is not plugged in and functions of of the battery.  
I can remove the battery and plug it in, it works. 
Both things accured at the same time (day before yesterday) AND my laptop is super slow all of the sudden.
Streaming movies is almost impossible, it's so choppy. Regular websites take forever to load and freeze randomly. 
It can't be out network, because all other laptops in our house work just fine. Exept mine. 
Notebook 15 -ish ,Touch screen.

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
