Boardview for Apple logic board 820-01814 (SAFFORO) in the .pcb format, 3.01 MB, with an LO31 tag in the name. Such files open in tools like FlexBV, OpenBoardView or ZXW-type software. They show where parts are placed and how nets connect, so you can follow a rail from connector to load or find the pads to measure. Confirm that the 820 number on the PCB matches, and use the matching schematic alongside it when checking values.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @LaptopsBoardview. Enginerys does not host this file.
