Component location document in PDF form for the Apple MacBook logic board 820-01598, packed into a 3.35 MB RAR. Apple uses the 820-xxxxx scheme for its logic board numbers, and location sheets show where each reference designator sits on the board. Technicians pair them with the matching schematic to find capacitors, resistors, ICs and test points while chasing shorts or missing rails. Extract the archive and open the PDF in any reader, and check that the 820 number printed on your board matches exactly first.
