MSI MS-171B1 schematic, revision A, supplied as an 839 KB PDF. MS-17xx style codes are used by MSI for its notebook mainboards, so this is very likely a laptop board, though the name gives no retail model. Use it to trace the charger and battery circuitry, system power rails, EC and power button logic, and to locate components and test points during short or no-power diagnosis. Confirm that the board code and revision printed on the PCB match the drawing before using component values.
