Apple schematic for the MacBook Pro A1287, the K19 project, under document number 051-7892 at the PVT stage, carrying the internal code name Cornhole. PVT marks the production validation build, so it should be close to retail boards, but confirm the 820-series board number on your logic board corresponds. Technicians use these Apple PDFs to follow the power sequence from the charger circuit through the main rails, locate test points and fuses, and check sensing lines when a board will not power on. Opens in any PDF reader.
