Archive for Apple logic board 820-3462 linked in the name to model A1425, packed as a 1.89 MB zip file. It most likely contains a schematic and possibly boardview data for that board. Technicians use these to follow the power-on sequence, measure rails like PPBUS and the standby supplies, look for shorts and locate parts on the board. Boardview content opens in tools such as OpenBoardView, while schematics open in a PDF viewer. Confirm that the 820 number and revision silkscreened on your board match this one.
