GPU not recognized after upgrading the GPU daughterboard

[JMD31]

Greeting, I have a Zbook 15 Fury G7 without dGPU and I've been attempting to upgrade it with one, it is a model 298B3AV with an i5-10400H CPU.

I had sourced a known working T1000 daughterboard for it with the correct part number(M17054-001) according to the info I found along with a new BEAM connector, making sure it was properly installed with the official HP guide on youtube, however it didn't show up in both Windows 10 and Ubuntu 20.04 LTS.

Device manager didn't recognize the card(checked the "hidden device" option) nor "sudo lshw" command in Ubuntu terminal, attempting to install the nvidia driver on windows failed with "no nvidia gpu is detected on your system" message while Ubuntu did installed the driver but "nvidia-smi" command returns nothing.

Performed multiple OS/Driver clean reinstall using Windows Boot Media creation tool/HP cloud recovery/Official Ubuntu 20.04 image with no avail, HP remote diagnosis UEFI only showed the intel iGPU, updating the BIOS to current version also yields nothing.

Since I have found similar varients of 15G7 that had a T1000 on PartSurfer with the same CPU so I assumed it should be a drop-in and play procedure, but it seems there's more to it and I am almost out of idea. Are there anything I have to do in order to make it work?

Try this driver from HP.

For a discrete graphics solution to work, the driver must come from HP and be for a supported operating system.

Sadly it doesn't work, after decompressing the files the startup never initialize, trying to manually install it also can't find the device.

How do you know it is working? 

Did the seller tell you it was working or have you seen it working on another example of your laptop?

I was shown images of it working on another G7 and judging from the imperfections on part I assumed it was the same one. It also radiates heat so it should be working to some extent.

While researching the issue I found out this socalled "Featurebyte" and instances of similar HP computers being locked out from certain features even when the user installed them afterward. It seems there are ways to circumvent it but it's out of the scope of this site. I'll now look in that direction and see if I get any result from it.

I would return it to the seller, if that is possible.  It is likely to be a non-working card. In my own experience with video cards, here is no such thing as  a partially working. The video card will either work or not.
