ASUS X550WE archive at board revision 2.0, packed as a RAR of about 268 KB. The name does not reveal whether it is a boardview or a schematic, but files of this size from ASUS are often boardviews in FZ format. Once extracted, a layout opens in boardview software such as FlexBV or OpenBoardView, which shows part placement on both sides and highlights every pin on a selected net. That speeds up finding test points and shorted components. Verify the revision printed on the PCB is 2.0, not the earlier 1.3 layout.
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 @cyberlanelectonik. Enginerys does not host this file.
