ASUS X1404ZA laptop mainboard boardview, revision 3.0, delivered as a ZIP archive. With it you can click any component to see its nets, trace power rails from the charger input to the CPU regulators and locate test points or the BIOS chip without guesswork. Extract the file and open it in a boardview program such as FlexBV, OpenBoardView or Boardviewer. Before relying on coordinates or part numbers, confirm that the board revision printed on the PCB reads 3.0, since other revisions may differ in 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 @cynetitsolution. Enginerys does not host this file.
