Sony VAIO laptop schematic for the MBX-266 motherboard, provided as a 1.13 MB PDF. MBX numbers are Sony's own designations for VAIO mainboards, while the actual board was often built by an ODM partner such as Foxconn, Quanta or Compal. Read the title block for the revision and use the diagram to trace power rails, charging circuits and signal lines, and to find components around a fault. Make sure MBX-266 and the revision printed on the PCB match the drawing before relying on it.
