T540p WLAN Upgrade to 8265 error 1802

[klausp1]

Hi,

I know that there are many articles about this problem, but could I have a specific answer?

I have a T540p, variant 20BE005YGE with a built-in Intel 7260 AC WLAN card.

Its FRU is 04X6007 and is working fine.

I wanted to upgrade to a newer Intel 8265 ACand I bought one naively at amazon.de at Amazon.

Its FRU is 01AX702, P/N G86C0007J510 and I am quite sure that I bought an original product.

Now I have the well known 1802 error that tell me this is a "Unauthorized network card".

I do not want to break my BIOS with some of the known solutions.

Is there any way to upgrade(!) to a whitelisted 8265 card in my T540p?

In the whitelist pdf "t540_fru_bom_20140108.pdf" I do find only 7260 cards.

That means I do not need a replacement, I wish to upgrade...

I must say that I am very surprised with this problem, because my opinion was that  Thinkpads  are the most serviceable devices.

And than such a serious restriction, also in the time after warranty period...?

Best regards,

Klaus

no, Intel 8265 card isn't whitelisted in T540p. This card's ID differ from the 7260's ones, so, the BIOS doesn't pass it over.

How would you perform that? By the card's ID changes within the card? It's impossible.
