Schematic for the Sony Vaio MBX-126 motherboard, credited to Quanta under the JE5 project code. Sony assigns MBX numbers to its boards while Quanta uses short platform codes, and both are typically visible on the PCB along with a revision. The PDF helps repair work by showing power rails, regulator circuits, enable signals and connector pinouts, making it easier to find a short or a missing voltage. No revision is stated in the name, so compare the title block against your board before trusting values.
