Boardview for the ASUS X507MA laptop mainboard in FZ format, a compact 66.4 KB file. The name gives no board revision. FZ files are opened with boardview viewers such as OpenBoardView, FlexBV or Boardviewer, which show the part placement, net names and pin connections. Technicians use it to locate components, test points and connectors, and to follow a net while measuring voltages or hunting shorts. Check the revision printed on your PCB, since layouts can differ between versions.
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 @notebookschematic. Enginerys does not host this file.
