Schematic for the MSI MS-1785 notebook mainboard, version 0A, supplied as a PDF inside a 6.85 MB rar archive. MS-xxxx is MSI's own board numbering, so this is an in-house MSI design. The diagrams let you follow power rails, check the power-up sequence, look up the EC and charger circuit, and read component values when hunting shorts or a missing voltage. Make sure the version marking on the PCB matches 0A before trusting part values.
