this error is usually caused by either running a old bios,

or running a new bios that also requires the ME firmware to be updated

to resolve either, update to the latest bios and also update the Management Firmware

directions to perform both are included with each SPxxxx update file

you can also safely ignore this error if you are not comfortable flashing your system

PER HP:  ( https://support.hp.com/ie-en/document/c06065035 )

• 972 Message: If message observed after BIOS update, Management Engine update, MEBx provisioning + disablement of AMT or CMOS button press please disregard message as this is works as designed. Press Enter to continue.
  These messages will be suppressed in a future BIOS planned in August 2018 and after BIOS versions. The message will be suppressed to alleviate customer intervention of having to press Enter to continue.
  HP may decide to allow the message back in future BIOS versions with a feature enhancement to allow for better automation ability.

Thanks for your support. If my computer working as only offline which means no internet connected, how can I update the bios and management firmware.

the answer isn't exactly a difficult one....................

download the necessary files on another system, then run said files locally on the system to be updated
