Repair documents for the Apple MacBook Pro 13-inch A1278, logic board 820-2530, project code K24, stored in a 1.31 MB RAR archive. Apple uses the 820- prefix for its logic board part numbers, and that number on the PCB is the most reliable match against these drawings. The package most likely holds the schematic, useful for diagnosing no-power faults, tracing the G3H and S0 rails and checking the charging circuit. Confirm the revision suffix on your board, since parts can differ between variants.
