Schematic diagram for the MSI MS-14A3 laptop motherboard, revision 2.0, packed as a PDF inside a RAR archive. MS- followed by four characters is MSI's own board numbering, so the PCB is MSI-designed. Use the pages to follow power rails from the charger and adapter input through the regulators, check EC and BIOS connections, and identify parts when diagnosing a short or a no-power fault. Any PDF reader opens it after extraction. Make sure the board shows revision 2.0, since earlier revisions may differ in layout and component values.
