I don’t understand your statement right now, but I also don’t know how to identify the component, I can’t access the graphics card when it’s installed.
Yes apologies I was just thinking of the video and how it was discovered.
Hmm! I suppose the card would have to externally connected by a cable 
On 22.05, they confirmed the replacement of the dGPU. Today is already 27.05 and no one has contacted me, just silence.
I still have mine with me because support hasn’t answered me yet about how we can proceed. Maybe I should test something with the second card.
