Schematic for the MSI MegaBook S425 laptop, board number MS-1022 at revision 0B, a 1 MB PDF. MegaBook was an older MSI notebook line, and this document covers the main board circuitry. Technicians use it to follow the power input and charging section, trace regulator outputs and enable signals, and identify components when a board shows a short or missing rail. The MS-10xx number follows MSI's own notebook numbering; confirm the PCB marking and revision match before replacing parts.
