Schematic of MSI mainboard MS-1431, revision 0A, in a 1.64 MB PDF; the Sec suffix in the name likely marks a secured or protected copy of the document. No laptop model is given, so identify the unit by the MS-1431 marking on its PCB, following MSI's own numbering. The pages help with tracing power rails, locating protection fuses and switching MOSFETs, and following clock, reset and power-good signals during no-boot diagnosis. Revision 0A is an early issue, so check the board revision before relying on exact component values.
