Boardview for an MSI notebook board MS-16K4, with the sub-number MS-16K41 and revision 1.0 given in the name, supplied as a ZIP archive of about 937 KB. A boardview maps every component, net and test point on the PCB, so you can find where a rail or signal physically sits while probing. Extract it and open the layout in a viewer such as OpenBoardView, FlexBV or Boardviewer. Compare the board number and revision printed on the motherboard before relying on part locations.
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.
