Schematic package for the Apple MacBook model A1502, drawn for logic board 820-4924 revision A, supplied as a 1.47 MB ZIP archive. Apple numbers its logic boards in the 820-xxxx format, and the suffix letter marks the revision, so compare the number silkscreened on the PCB before trusting rail names or part values. Technicians use such diagrams to follow power sequencing, trace signals between connectors and the SoC area, identify protection circuitry and decide where to measure when a board will not power on or shows a short.</div>
