PDF schematic for the Mantis CML platform, Wistron board 18778-1 with the additional reference 4R47G, delivered in a 7.31 MB RAR. CML points to Intel Comet Lake. Five-digit numbers with a dash suffix follow Wistron's numbering, and Wistron builds boards for Dell and other brands. A circuit diagram like this lets you follow power rails, enable signals and the power-on sequence when chasing a no-power or short-circuit fault. Open it in any PDF reader and confirm the 18778-1 marking on your board.
