Sony laptop schematic for the MBX-226 mainboard, with the M9A0 MP code in the name indicating the mass-production build of that design. The 928 KB RAR contains the PDF circuit diagram used on VAIO-family boards that follow the MBX numbering scheme. It helps when tracing power sequencing, charger circuitry and signal paths between the chipset and connectors, or when locating the source of a short on a rail. Extract it and open with a PDF reader, then check that the MBX number printed on the PCB is the same before relying on component references.
