Compressed repair package for the Lenovo Y510 notebook, packed as a 1.23 MB RAR. The name gives no board number, revision or document type, so open it and confirm whether it holds a schematic, a boardview or both. A same-size archive elsewhere references a Wistron B2M design, which may be the same material. Before relying on it, match the board number printed on your PCB, then use the drawings to check rails for shorts, find test points and follow signal paths around the charger and power circuits.
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.
