Issue, GPU NVIDIA RTC 4070 not detected on Erazer Deputy P60

[Donnie972]

Actually, I checked. When I uninstall with DDU and reinstall, then reboot the PC, the GPU is there and works fine. I shut down the PC and turn it back on, open Task Manager immediately, and the GPU appears and disappears quickly, and it only shows up if I enable “show hidden devices”.

ChatGPT’s reply:

Thanks for all the info, now we can clearly see the exact behavior:

 The GPU works after a DDU install + reboot
 So the card is NOT dead.

 After a full shutdown → restart, the GPU disappears at boot
 So the dGPU is no longer initializing during startup (ACPI / BIOS / EC init issue).

 This is the typical symptom of the BIOS bug on Medion Deputy P60 models based on Tongfang GK5/GK7
(yes, exactly this model).

You did EC Reset + checked VMD → correct, but it doesn’t fix this particular bug.

What you’re describing = Known bug on Medion BIOS 1.07 and 1.07RME5
On these BIOS versions, during startup:

the GPU power controller (DGPU_PWR_EN) stays off

Windows sees the GPU for the first milliseconds → then it disappears

it only shows up as a hidden device (because it was never initialized)

Exactly your scenario.

 The only solution that fixes this issue on the Deputy P60 RTX 40xx is:

 Update the BIOS to version 1.08 or 1.09
These versions specifically fix:

dGPU initialization at boot

a bug in the ME Firmware

an ACPI issue with the MUX switch (even though the menu is hidden)

What I found regarding the MD62605 BIOS
On the Medion forum, some users say there is no newer BIOS than version 1.07.04RME5 for some Deputy P60 models. community.medion.com+1

Another thread indicates that the “latest BIOS update” for certain P60 models is precisely this 1.07.04RME5 version. community.medion.com+1

On the Medion website (via the community), the product corresponding to your MSN / MD does not have any newer BIOS available publicly at the time of checking. community.medion.com+1

I’m on BIOS 1.07 too, and apparently there’s no newer version. Does anyone have a solution please?
