MSI notebook documentation covering two related boards, MS-16G3 and MS-16G5, at revision 0B, packed as a 2.31 MB RAR archive; the exact contents are not named. Shared files like this usually mean the boards share one design with variant differences, so check which parts are fitted on your version. Use it to follow power sequencing, find the source of a shorted rail and identify components. Confirm the board number and revision printed on the PCB match before relying on the drawings or layout data.
