Schematic for MSI motherboard MS-16Q41 in a 6.32 MB RAR archive, most likely holding a PDF of the circuit diagram. MSI uses the MS- prefix with a model code and a final version digit, which should match the label on the PCB. After extraction the drawing is used to follow power rails, check the standby and charger stages, and locate components on a shorted line. The file name gives no revision letter, so compare the sheet headers with your board before trusting pinouts or values.
