Schematic for the MSI Megabook S420, motherboard MS-1412 revision 1.1, packed in a 1.00 MB RAR that holds a PDF. The board numbers MS-1412 and MS-14121 follow MSI's own numbering, in which the extra digit denotes the PCB variant. Open the PDF to trace power rails, check component values and follow signals between the chipset, EC and power controllers. Confirm that the revision printed on your board is 1.1 before relying on the circuit details.
