Thinkpad T410 Motherboard replacement

[Temetka]

Hello all,

I love my T410 very much. However I have an issue with it. The motherboard that is currently installed has the 256MB Nvidia 3100M GPU. I would very much like to upgrade it to the 512MB version.

What is the appropriate FRU for my machine? The machine type is: 2522-26U.

Thanks.

I'm sure you have heard of the HMM! http://support.lenovo.com/en_US/detail. ... MIGR-74470

Yeah, yeah.

I was being lazy about it and hoping someone would just give me the FRU or an e-bay link and say, "Here Temetka, buy this."

But alas, you have foiled my scheme.

Curses!

Here's what I found so as for the compatible FRU's for my system:

System board assembly, discrete graphics 512 MB, POP, RPTA-b, iAMT, TPM 75Y4057
System board assembly, discrete graphics 512 MB, POP, RPTA-b, iAMT, non-TPM 75Y4058
System board assembly, discrete graphics 512 MB, SMB, RPTA-c, iAMT, TPM 75Y4146
System board assembly, discrete graphics 512 MB, SMB, RPTA-c, iAMT, non-TPM 75Y4147


POP / SMB - What's the difference?
iAMT - Is this the Intel Active Management Technology?
TPM - Trusted Platform Module, I presume?
RPTA - ??? No clue, what this is all about let alone b vs c.

My machine type is 2522-26U. I have the webcam, fingerprint, bluetooth, express card, sd reader, etc. So given the machine type I have, which board do I want? I assume one of the TPM variants because I have the fingerprint reader.

Thanks
