Way too many steps in my opinion. First, the battery should be removed. I saw no reason to remove keyboard, folding it over was enough. Also, saw no reason to remove PRAM battery, I did disconnect it, however. The AirPort card didn’t have to be removed, either. Once the shield was removed along with the heatsink, the processor board just popped right out. When replacing board, make sure the little tabs are in their slots since the board won’t push back in all of the way. Thanks iRobot!
