Compressed package, 177 KB, linked to Apple logic board 820-3071 and also carrying the reference 051-8974 with a resolvedD2 tag. In Apple numbering, 051-xxxx typically identifies the schematic document that belongs to an 820 board, so the archive most likely holds schematic material, although the small size suggests a compact file. Extract it and check the contents before use. Match the 820 number on the PCB, then use the drawings to follow power rails, check signal paths and narrow down shorted components.
