battery calibration not working

[txgaryl]

My new laptop is saying my battery needs to be calibrated.  I charged to 100% and left it plugged in for over 3 hours as the instructions say but when i run the test again it keeps saying it needs to be calibrated.

Hello @txgaryl 

There is a know bug in HP Support Assistant...

(1) Test your hardware Using the HP PC Hardware Diagnostics (UEFI)

https://support.hp.com/us-en/document/c04499777

( Component test <power> for power supply and battery is also included )

See how it works:

(2) If everything (1) is fine, ignore the HP Assistant Warning to calibrate your battery

(3) If HP Diagnostics UEFI is telling you to calibrate the battery, come back to here and I will help you in a 2nd step ...

Thanks for the reply.  I ran the PC Hardware Diagnostics Power supply test, and it came back saying:

Battery check - primary - calibration required (20)

Lower in the panel it said Component Test - PASSED

What should I do next as it seems to be saying Calibration is needed?

Thanks for your help.

Hello @txgaryl 

Sorry to hear that you are having problems ... 

Do the following trick ...

(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 popup notification

(2) Shutdown your notebook/computer

(3) Remove battery, remove ac adapter, 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.

(7) If your battery level is too low and you are loosing your battery capacity too fast, your battery has to be replaced...
