Circuit schematic for the Sony VAIO MBX-202 mainboard, built by Foxconn under model code M790 with revision 1-01. The 788 KB PDF opens in any viewer and supports searching by reference designator or net name. Use it to follow voltage regulators and their enable signals, measure test points during no-boot diagnosis and isolate shorted capacitors or MOSFETs. The Foxconn code identifies the ODM behind this Sony-numbered board, and the MBX number on the PCB should match before you work from the drawing.
