Battery showing 255 % available (plugged in)

[sahit]

Hi,

Suddenly my notebook got shut while on charge and after restarting it was working only when plugged in. The battery was showing 100% charged and its health was good while checked in command prompt.

Later after an hour while using it (plugged in only), again got shut down suddenly and after restarting it was showing '255 % available, plugged in'. The battery icon was with a cross mark.

I replaced my old battery with new one in October 2019.( new one : 4-cell, 41 WHr 2.8AH Li-ion battery HP 756743-001).

What was the problem and how to fix it?

Hi @sahit,

Welcome to the HP Support Community. 

Please create a New User Account and check if the battery still charges up to 255% only on the New User Account

Hi,

Today also the notebook couldn't start while I tried normally. It started after connecting to power source only and today the white cross on battery didn't show up and it was showing as 96 % available (plugged in).

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 😊
