UPDATE:
So I did managed to reflash the BIOS in factory mode, however even after entering the Feature byte I found with T1000 listed on PartSurfer it still can't detect the GPU installed, so I think I am going to call it quit for now since I had spent too much time on this yielding no result.

Attached below is a clean factory mode BIOS (32m) I got, for 16m EC refrence #47 of this thread: [URL="https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/bios-requests-only/101596-hp-zbook-fury-15-g7-bios-password/page3#post3593359"]HP...

Greetings,

So I have acquired this Zbook fury 15 G7 (model 298B3AV with i5-10400H ) off Ebay, seller claimed it have a T2000 but suprise, the GPU port is wide empty so I am trying to upgrade it with one.

I got a second-hand T1000 daughter board which is claimed to be working, and I made sure everything were in order including other part I were supposed to install along with it, but the laptop can't detect the GPU and it's not even showing up in BIOS/Device manager.

I am not sure for this model if I can just slot in a GPU and it would straight up works, while...

Hello! I thought upgrading a HP laptop were just like other drop-in upgrade but apprently it's not, so I am seeking answer on this forum, this will be one of my prime certified HP moment.
