Apple A1370 logic board 820-2855 revision A archive, about 1.36 MB, with the model number repeated in the name. A1370 is the case model marking and 820-2855 the PCB number printed on the board. The package probably contains a schematic, possibly a boardview as well. Match the number and revision on your board, then use the drawings to measure rails, follow signals, locate test points and diagnose shorts or dead power circuits.
