Schematic in PDF form for the Apple MacBook logic board 820-00239, compressed into a 5.24 MB RAR. The board number is the key identifier, since Apple 820 numbers are printed directly on the logic board. The diagram covers power sequencing, rail names, charging circuitry and signal paths, used to diagnose no-power, no-charge or no-image faults. It works best alongside the boardview for the same number, so parts found on the schematic can be located physically. Verify the 820 number before relying on it.
