Apple A1278 logic board package for board 820-2936 revision A, delivered as a 1.63 MB RAR archive. The 820- number is Apple's logic board part number and must match the silkscreen on your PCB for the drawings to be reliable. Inside you can expect schematic and possibly boardview data for diagnosing power, charging and boot problems. Use it to measure rails in the power-on sequence, locate components and find shorts, and check which files are present after extracting with WinRAR or 7-Zip.
