Sony VAIO motherboard schematic for MBX-194, engineered by Foxconn as model M780, in a 1.80 MB PDF. No revision is stated in the name, so compare the board's silkscreen revision with the title blocks inside the document. Technicians rely on drawings like this to trace the power path from the adapter jack through the charger and regulators, check power-good handshakes and identify the parts loading a shorted line. Sony assigns MBX numbers to boards from several makers, and this one is a Foxconn design.
