Schematic collection packed as a 270 MB RAR file and labelled Nvidia 1000, apparently grouping graphics-related diagrams of that series. The file name carries no board numbers, models or revisions, so the archive has to be opened to learn exactly what it covers. Diagrams like these are used to trace GPU and VRAM power circuits, check enable and power-good signals and locate components when chasing a short on a rail. Compare the board identifier silkscreened on the PCB with each document before using it for a repair, since similar designs differ between revisions.
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 @videocard_notebook_resistance. Enginerys does not host this file.

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