Laptop is automatically shutting down at 24- 31%(any percent between them in random) battery

[Swapnamoy_4345]

I am facing auto shutdown problem in my laptop. At around 30% charge , laptop shuts down automatically without giving any alert. I have done hp hardware Diagonastic test. It says battery UNKNOWN and also is getting cancelled.

I have removed my battery , and then full charge , then when it becomes below 30% , it turned off automatically. i can not drain the battery fully. I have uninstalled drivers. But nothing happened. 

I had replaced my battery 5-6 months ago. This is new battery.  

Also I have measured the output of laptop adapter . It's reading is 19.88 volt. But the fixed output voltage that is printed in my adapter is 19.5 volt. 

Please help me , how i can fix it.

@Swapnamoy_4345, Welcome to the HP Support Community!

I understand the Notebook shuts down even when there is 24-30% of the battery charge left. Are you using a compatible HP battery?

Reinstalling Microsoft ACPI-Compliant Control Method Battery under device manager may resolve this issue. Let us try these steps: 

Step 1: Click the Windows “Start” button and right-click “Computer.”

Step 2: Click “Manage,” then “Device Manager.”

Step 3: Click the “Batteries” section. A list of devices will appear.

Step 4: Right-click the “Microsoft ACPI-Compliant Control Method Battery” device and click “Uninstall.”

Step 5: Click the “Action” menu item and “Scan for Hardware Changes” to reinstall the driver.

Restart the computer and check.

If the issue persists, I recommend you update the BIOS from this link, enter your Product number or name.

Hope this helps! Keep me posted.
