W520 Motherboard Compatibility - are they all interchangeable?

I've got a W520 with a failed motherboard.  The system FRU is 4276-3KU.  I've been looking at replacement motherboards in the hardware maintenance manual here:

 

http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/t520_t520i_w520_hmm_en_0A60078_08.pdf

 

Of the 16 or so W520 motherboards, it seems that my system is only compatible with 3 or 4 of them.  Is that correct?  I was under the impression that all W520 motherboards were interchangeable.

 

The reason I ask is that I would like to obtain a motherboard with K2000M graphics and RAID, but my system FRU is not listed as compatible with those motherboards.  I don't need WWAN, but I do need the msata port, in case that makes a difference...

they are interchangeable, the difference in motherboard is really down to GPU, RAID, TPM, and AMT, these are non removable parts.

Just a heads up, they aren't all quite compatible.  My old motherboard has a 6-pin fan connector, and the one I purchased has a 4-pin connector.

My original FRU was 04W2028, my replacement FRU is 04W2029.  Original had K1000 graphics, replacement has K2000 graphics.

Re: W520 Motherboard Compatibility - are they all interchangeable?

Is there any place/doc where I can find whether 01AY528 and 01AY530 are compatible/inter-changeable???

 

The laptop in question is: 

Yoga 12 Laptop (ThinkPad). I was trying to initiate a different thread but was not able to. Will really appreciate a response from someone. 

 

Thanks

Best Regards

HG.
