Sony motherboard documentation for the M720 project, board number MBX-182, revision 1.0, in a 1.05 MB RAR archive. M720 is the ODM project code, while MBX-182 is the Sony board designation used on VAIO machines. The size suggests a schematic, useful for following power sequencing, testing rails and locating parts when diagnosing no-power or no-boot faults. Check that both the MBX number and revision 1.0 match the markings on the PCB before relying on component values.
