Schematic for the Apple logic board numbered 820-02536, as a PDF in a 4.09 MB rar archive; the name gives no Mac model. Apple's 820 prefix identifies logic board designs, so match it against the number silkscreened on the PCB. Schematics like this show power-rail names, the power-up sequence, the SMC-related signals and component values, which is essential for working through faults methodically. Use it together with the 820-02536 boardview, which carries matching net names, to move quickly from diagram to the physical board.
