[REQUEST] HP ZBook Fury G9 Undervolt unlocking
#1
Hi all,

I was trying to unlock the undervolting for the BIOS of HP ZBook Fury G9. The BIOS file is available for downloading here and after extracting the BIOS image can be found here. I was looking for the usual suspects for overclock lock cfglock etc. and I could not find anything there. UEFITool extracted sections can not be converted to text via ifrextract.exe. So no clues how to enable the undervolt unlocking information. I was also recommended to check the tools like H2OUVE but it could be that my BIOS is too new or I am lacking the knowledge to use them properly.

Can you help me with unlocking the undervolting? The CPU is a 12950HX, so it is not locked from undervolting.

Thanks,
DM

By the way, another interesting point is, I had some candidates for modification and tried modifying a variable in CpuSetup via setup_var. I set the variable to zero, read it back and it was zero, then exited grub and after system restart I loaded the grub again and the variable was reverted back to the original value. Looks like there's a mechanism monitoring the BIOS variables.
