RAR package for Sony PCG-7184L and PCG-7192C laptops, noting Foxconn as the board maker. Sony often contracted Foxconn as an ODM, so the drawings inside may follow Foxconn page layouts and naming rather than Sony conventions. The archive is about 1 MB, a size consistent with a PDF schematic, but its exact contents are not described. Use it to check power rails, the charger stage and connector pinouts. First confirm that the board in hand is the Foxconn-built version for these PCG models.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @generalschematics. Enginerys does not host this file.

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