Hey guys, I have an old iBook G4 with a dead logic board, everything works fine for about 10-15 minutes, then the display stops responding. The hard drive continues to spin, processor still chugs, etc. I'm going to leave it running iTunes in a few minutes and when it freezes, hit the space bar to see if the actual machine still responds. (In which case I would be sure that it's the video card, or some cable in that area.) My question: I'm looking on eBay for replacement logic boards, and I'm wondering how specific/universal they are. Obviously, it needs to come from a 14" iBook, but does it matter what processor speed? Eg. Will a board from a 1.2GHz iBook work? I have the iFixIt guide, and I'm not too worried about wrecking the thing, so it's just a matter of making sure I get the right part. (How about this one: Linkety ?) Thanks!
