Apple logic board schematic for board number 820-02773, provided as a PDF in a 22.8 MB ZIP archive. Apple uses 820-xxxxx numbers for logic boards, and the number is printed on the PCB, so check it before using the drawings. The schematic helps you follow power rails such as PPBUS, trace the SMC and power-sequencing signals, and find the parts behind no-power or short faults. Use it with a matching boardview for part locations.
