Boardview package for the ASUS GX701LXS, a ROG Zephyrus model, with the board revision given as REV 1.3. It is supplied as a 12.2 MB RAR archive, which should be extracted before loading the board file into a viewer such as OpenBoardView or FlexBV. With the layout open, you can locate parts by reference designator, highlight nets to see where a signal or rail travels, and find accessible test points for probing. Check that the revision printed on your motherboard is 1.3, because component placement can 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 @BoardSchematic. Enginerys does not host this file.
