Archive of 8.31 MB for the Apple A2141 model on logic board 820-01700, with an x970 tag that may be the project code. Apple numbers its logic boards in the 820-xxxxx format, and that number is printed on the PCB for identification. The contents are not listed, so check whether it has a schematic, a boardview or both. Such documents are used to trace power rails, find the source of a short, locate test points and follow signals on a densely packed MacBook board. Match the full 820 number before trusting it.
