Package for the Apple MacBook Air A1370, labelled with project code K78. The 1.26 MB RAR most likely contains schematic pages for that logic board, though the name does not list its contents. Use it to trace power sequencing, locate components and narrow down shorts. A1370 shipped with more than one board design, including one labelled K99, so read the 820- number on the PCB and make sure it corresponds to the K78 board before working from these drawings.
