I am trying to find replacement parts for my MBP, as it needs a new DC-in board and screen. I have been looking on eBay, but I'm quite confused with some of the model numbers. Could someone please explain the difference/correlation between model numbers like A1150 and MA895LL? I am quite confused as to what is what. Here are my MBP specs if anyone can help: 15.4" Matte Screen 2.33Ghz Core 2 Duo processor 2Gb RAM Nvidia 8600M GT (unknown MB, don't have a working screen right now ) Basically, if someone could help me figure out what DC-in board I'll need and what screen, that'd be fantastic. If not, helping me figure out what model numbers to look for would be greatly appreciated, and I'll go from there.
