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:
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...

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.

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.
