Apple logic board schematic for board 820-4924, with 1502 also in the name, likely a Mac model reference, delivered as a 2.88 MB PDF. Apple uses the 820- prefix for logic board part numbers, and the number on the PCB is the reliable way to confirm a match. The schematic shows power rails, the SMC and power-up sequence, charging circuitry and component designators, so it helps locate shorts and failed parts. Pair it with a boardview for the same 820 number for easier component location.
