Battery Calibration

[JamesNel1]

Hello,

My HP support assistant indicates that the battery should be calibrated.  I followed the instructions below (from HP website), and the assistant still shows that the battery needs calibration.  I have run the battery test, and the battery is fine.

1) Open the Windows device manager and uninstall the "Microsoft ACPI-Compliant Control Method Battery"

- Right click on "Microsoft ACPI-Compliant Control Method Battery"

- Click "Uninstall device"

- Confirm your choice if you see a pop-up notification

(2) Shutdown your notebook/computer

(3) Remove the battery, remove ac adapter, and press and hold the power button for 30 seconds.

(Note: If do not have the technical skills to remove the battery (most notebook has to be diassembled !) , just start the notebook and go directly into the bios (ESC/F1/F2/F10) and let the notebook stay there or run HP Diagnostic Test loops to drain the battery (don't connect the AC adapter !) until it is switching off automatically

(4) Install battery, plugin ac adapter and wait until the battery is fully charged (don't start the windows operating system !) and check the charging led.

(5) If you do have no charging led, wait at least 2 hours ...

(6) Start your notebook/computer, now the windows battery management system is synchronized with your installed battery. Normally it should show 98-100% battery level.

How do I calibrate the battery?

Any suggestions are much appreciated.

@JamesNel1, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

You've already taken a number of the right steps, including following the manual calibration method and confirming the battery is in good health. Since HP Support Assistant still indicates that calibration is needed, it’s likely that the issue is with how the calibration process was completed or a software mismatch. Here's an official guide you can refer to: HP Notebook PCs - Testing and calibrating the battery (Windows) | HP® Support

Also, Update BIOS and Drivers

Open HP Support Assistant.

Click Updates and install everything related to:

BIOS

Battery or power drivers

I hope this helps.
