Sudden shut down between 40-50

[itssaurav]

Recently from last 2 days, it suddenly shuts down without any battery warning or sometimes just pop up for a blink of eye displaying low battery and then black out, and doesn't switched on until plugged to the AC supply, and when turned on it shows up the percentage which was during the time of shutdown, most the times this happens when it between 40-50% battery. All the drivers are updated and no heating issue already checked.

And even after that when a remove the charger its works fine for a few minutes but the same happens when reaches below 40.

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
