RAR package for the Apple A1278 MacBook Pro 13-inch with logic board 820-2565 revision A, about 2.09 MB. It most likely contains the schematic and possibly a boardview for this unibody generation. Technicians use it to follow power rails from the charger IC onward, identify a part pulling a rail to ground and locate test pads near the CPU and GPU areas. The A1278 used various 820 boards over its run, so confirm that 820-2565 is printed on your logic board before you start measuring.
