Update not available for UEFI in Windows 11 version 25H2

[rom57]

Battery calibration cannot be proceed because UEFI is not updated. HP website doesn't provide any update for Widows 11 version 25H2. Please provide some advise related to the battery calibration and UEFI update.

@rom57,

Are you referring to the HP PC Hardware Diagnostics UEFI tool or UEFI BIOS update file?

Provide the product number of your notebook too.

I can't use UEFI tools to calibrate the battery because I get the message to update the PC Hardware Diagnostics UEFI tools. 

Product number: 9S1R6UA#ABA

Thanks.

Run the downloaded file as administrator and follow the on-screen instructions to install the diagnostics UEFI on the hard drive.
