Schematic for the ASUS A3N laptop, 1.01 MB in PDF form, without a board revision in the name. The diagram set helps trace the main voltage rails, locate protection fuses and MOSFETs, and follow the power-on signals when a board does not start. A standard PDF reader opens it. Read the revision from the title block and compare it with the silkscreen on your board, since component positions and values may vary between revisions of the same model.
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 @hrtechno. Enginerys does not host this file.
