Service archive for the Apple A1278, the 13-inch unibody MacBook Pro, built around logic board 820-2936 revision A. This 1.67 MB RAR is expected to carry schematic and possibly boardview data for that board. It helps with tracing the power-on sequence, checking SMC and charger related rails, finding a shorted capacitor and locating connectors. Several 820 boards were fitted to the A1278 across its years, so verify that the number etched on your PCB is 820-2936 before relying on the nets and part references.
