Boardview for MSI notebook board MS-17G31, revision 1.0, compressed into a 236 KB ZIP. MSI identifies its laptop boards with MS- and a project code, the last digit indicating the board variant, so the matching model name should be taken from the PCB or service label because the file name does not give one. A boardview viewer lets you highlight a net, find where a rail goes and pinpoint parts for replacement. Before trusting the placement, check the silkscreened MS-17G31 and revision on your board.
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.
