Battery issues

[SK1596]

Few days back my laptop started shutting down at 40%.I asked in HP community and an expert adviced me to do calibration of battery. I haven't done that yet since I thought buying a new battery instead. But now I am experiencing strange behaviour... When i plug in charger, few moments later the lights switch from orange to white even when it is just 50% charge . When I plug out and again plug in, it changes to orange and after few moments again switches to white.Also i think my laptop is charging much faster than before.

I have gone through your Post and would like to help

Have you tried with a different AC Adapter to check if you face the same issue?

Please reinstall the Microsoft ACPI Compliant Control Method Battery

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 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 😊
