MSI boardview for mainboard MS-16R81, version 2.0, supplied as a compact 156 KB zip archive. MSI designs its own laptop boards and labels them with the MS-xxxxx pattern, with the trailing digit and VER marking indicating the PCB variant. Load the extracted file in OpenBoardView, FlexBV or a similar viewer to find component locations, pin nets and test points while measuring rails or isolating a shorted capacitor. Check that the silkscreen on the board reads MS-16R81 Ver 2.0, since other revisions can move parts around.
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.
