Laptop motherboard schematic for the MANTIS CML project, board 18778-1 with the 4R47G suffix, a 5.35 MB PDF. CML refers to the Comet Lake platform generation. The five-digit dash number with a suffix follows Wistron's board coding, so this is a Wistron-designed board regardless of the brand on the lid. Use it to trace charger, VCORE and memory rails, follow the EC and power button path, or pin down a shorted component. Match the number printed on the PCB, and open the file in any PDF reader.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @afsschematicfree. Enginerys does not host this file.
