Lenovo-related RAR archive of 1.05 MB for a Foxconn board coded S04. The name gives no machine model or revision, so match the code against the motherboard silkscreen before trusting any pinout. The contents are most likely a schematic set, openable in a PDF reader once extracted. Use it to trace power rails, check MOSFETs in the CPU voltage regulator, find test points and work out why a board will not power on.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
