ASUS X555LA motherboard archive, revision 2.0, packed into a 216 KB ZIP. The name gives no list of contents, but the small size suggests a boardview layout rather than a schematic. A boardview viewer such as OpenBoardView or FlexBV displays part placement, nets and pins on both sides of the PCB. Before relying on it, confirm the model and rev 2.0 marking on the board itself. It is handy for locating components, finding test points and tracing a rail back to its source when hunting a short.
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 @ITHINKHS. Enginerys does not host this file.
