Service material shared by the ASUS A8E and A8S notebooks, in a 1.62 MB RAR archive whose name does not say whether it is a schematic, boardview or other document. Its size is typical of a compressed schematic PDF. Check the extracted contents first. For a circuit diagram, it helps trace power rails, standby circuits and signal paths across these closely related models. Confirm which model and board revision each page applies to before using it on a specific mainboard.
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 @boardviewsandachematics. Enginerys does not host this file.
