Schematic in PDF form for Apple logic board 820-02098, compressed into a 4.82 MB RAR archive; the name does not state the Mac model. Apple numbers its logic boards with an 820 prefix, and the full number is etched on the PCB, so compare it before using the diagrams. A technician uses the circuit pages to follow power sequencing, identify rail names, check expected voltages and find which components sit on a shorted line. Pair it with the matching boardview for physical part locations.
