Business Notebooks

I have tried using the update utility under windows 10, windows 11 and ubuntu. I have tried using windows update under windows 10 and windows 11. I have tried the software center update in ubuntu. I have tried creating recovery usb drives with several usb drives with several versions of the bios all with the /HP/DEVFW/firmware.bin folder structure. I also put the file in /HP/BIOS/New/firmware.bin. I have tried the network bios update from within both the F10 menu and the diagnostics menu. Nothing has worked. I am running the bios from the factory, 01.02.01. I have tried versions 01.03.01, 01.07.00, 01.08.00, 01.09.03 of the bios bin file. I have tried exporting the bin from the "HpFirmwareUpdRec64.exe -w" command and using that exported .bin. I have tried copying the U82_xxx.bin file into those folders above and renaming it firmware.bin. I have tried copying that file without renaming it to those folders. I have tried the later versions of the bios on the EFI partition of the drive under windows 10, windows 11, pop_os! and ubuntu.I have not had bitlocker enabled on the drive, ubuntu was installed without disc encryption.

Why can I not update the bios?  Oh and the serial number within the bios and on the sticker hp's support website says it's an older 2000-xxx laptop. not the elitebook 865.
