Schematic for the Apple A1278 MacBook Pro with logic board 820-2565-A, in a 3.06 MB RAR archive containing the PDF. Apple uses 820-xxxx numbers for its logic boards, with the letter suffix showing the revision. A1278 is the model number found on the bottom case, which covers several board generations, so the 820 number printed on the board is the one to match. The diagrams help with tracing power rails, checking the SMC and power sequence, and locating parts behind a short.
