MSI notebook mainboard material for board number MS-16371 at revision 1.0, packaged as a RAR archive of about 974 KB. The file name does not include the laptop model or say what the archive holds, so expect a schematic or boardview and verify after extraction. MSI laptop boards use five-digit MS-1xxxx codes printed on the PCB, which is the reliable way to match documents. Use them to trace charger and system rails, follow signals through the EC and locate components when chasing no-power or no-boot faults.
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 @IT_SERVICE_WORLD. Enginerys does not host this file.
