Bios firmware update failed - error 259

[Ron22690]

Hi, I have a HP ZB15G7,

following a windows 11 failure, I have reinstalled windows and downloaded the softwares/hardware updates using the HP support assistant and the Windows update.

However 2 items fail to be updated:

Whatever I stop antivir to work and I unlock the drivers and partitions (bitlocker stop on 3 drives/partitions)

I receive the  following results:

- HP BIOS and System Firmware (S92) (Failure Code: 259) 

 - 

- Without passing by the HP assistant, same result

 - Updating directly the bios by making f10 at the PC start => another error message

Could you please let me know how to solve this issue by providing a step by step tutorial?

Thanks in advance for your kind help

Warm regards,

R

Hi @Ron22690 

Welcome to the HP Support Community.

Thank you for posting your query.

I understand that the BIOS update is failing with error 259 through both HP Support Assistant and the normal BIOS update method. As the next step, please install the latest BIOS update using the official HP BIOS update link provided for your specific ZBook model https://support.hp.com/in-en/drivers ;

Please revert if you receive the same error.

Take care and have an amazing day!
