ZIP archive of 101 KB for revision 2.0 of the ASUS X553MA motherboard. The name does not describe the contents, though the size points to a boardview rather than a schematic PDF. A sibling file exists for rev 2.1, so read the revision silkscreened on your board and pick the matching one. Open the layout in a boardview program such as OpenBoardView or FlexBV to find parts by reference, trace nets between components and locate test points while diagnosing no-power, no-charge or short faults.
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.
