Battery Icon show Unknown remaining

[Wayneng]

Hey guys,

I used this notebook for few years. Of course the battery life dying eventually. Therefore, I purchase an original internal battery with the same model HP SE03XL Rechargeable Battery. 

After I install the new battery, my taskbar battery icon show "unknow remaining" but I've checked on Device Manager and the system is detected my battery.

I tried uninstalling the driver>Scan>reboot, but the icon is still showing "unknown remaining".

@Wayneng Greetings from the HP Community!

I have a few steps listed below that should help you resolve this concern:

Unplug the charge, Turn off the laptop and turn it back on after 30mins.

Reinstalled Microsoft ACPI-Compliant Control Method Battery under device manager:

1) In the search box, type and open “Device Manager”.

2) Expand “Batteries”.

3) Right-click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there.

4) Click on “Uninstall”.

5) At the prompt put a check in the box to remove the current driver

6) Shutdown the computer.

7) Remove the battery for a minute and then put it back in. (Skip this step if you have a non removable battery)

8 - When the computer comes back up it should automatically find the driver.

9) Go to Device Manager.

10) Expand Batteries.

11) Right-click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there.

12) Click "Search automatically for updated driver software"

Do the same thing with Microsoft ACPI-Compliant Embedded Controller.
