MSI boardview for mainboard MS-16R81 version 2.0 in BDV format, packed into a 129 KB RAR archive. MSI manufactures its own laptop boards under the MS-xxxxx numbering, with the version marking identifying the PCB revision. Open the layout in OpenBoardView, FlexBV or another BDV-capable viewer to locate components, read net names and find test points while chasing missing voltages or shorts. Make sure your board reads MS-16R81 Ver 2.0 on the silkscreen before relying on the part positions shown.
