MSI MS-14C11 notebook boardview, packed in a 447 KB RAR archive. MS-14C1 is MSI's in-house board number, the trailing digit typically indicating the PCB version, and it is printed on the board itself. Check that it matches before work. The layout maps parts, pins and nets, so you can follow a power rail, find a failed component in the charging or VRM area, or identify connector pinouts. Pair it with the schematic where available. Open the file with FlexBV, OpenBoardView or another boardview viewer.
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 @BoardSchematic. Enginerys does not host this file.
