Sony VAIO mainboard schematic, PDF of 1.82 MB, for board MBX-156, which corresponds to the Foxconn MS20 design at MP (mass production) stage. MBX numbers are Sony's own board identifiers, while the actual engineering was done by the ODM Foxconn, whose MS project code also appears. Repairers use these sheets to trace power rails, power-good chains and charger circuits and to find components around a short. Check that the MBX number and revision on the PCB match before relying on values; open in any PDF reader.
