Wow, been a while since I actually posted anything. I have a late 2006 black MacBook with 2GHz Core2Duo and Intel GMA950. Everything on it works great, just painfully slow graphics due to being nearly 8 years old. I came across someone selling an A1181 logic board on craigslist that is from a newer model with the X3100 graphics, and I'm wondering if it's at all compatible with the model I have. I've looked a bit online but it's hard to find info since it's such an older model. The part number on the board for sale is 820-2279-A and the part number for my installed board is 820-1889-A. Most things I've found have said that the same board number is always interchangeable no matter what processor it has, but that different ones may work or may not. I've looked over a lot of photos of both models and it looks like all the connectors are the same, but I can't see well enough to judge certainly. I read a couple places, mainly some threads on ifixit, that the 2006 models weren't energy star rated, and that the newer ones that are energy star rated have a different battery connector. It's only 60 bucks for the board, heatsink and fan, and airport card, and if it doesn't work I can always resell it, just wondering what my chances at success are. Any info or a point in the direction of any info would be awesome, thanks guys.
