Answer to: Breakdown of CECHHxx modelI think I had something similar happen to me. There were references to a thin 'control board" and a memory card reader; neither of which my model had. There were also extra thermal pads for RAM I did not have either. As the pieces in question were not photographed or addressed in any manner I just removed them in between the other identifiable steps. Labels the screws and set them aside in a container. Treat the posted repair guide as loose set of dis-assembly tips rather than explicit instructions and you'll be OK.
