RAR-packed PDF schematic for the Sony VAIO VGN-AW series, covering motherboard MBX-194 with project code M780. Extract it with WinRAR or 7-Zip, then open the PDF in any viewer. The drawings are useful for following the power path from the DC jack through the charger and main regulators, locating feedback resistors and confirming which rails should appear at standby. Sony stamps the MBX number on the PCB, so confirm it is MBX-194 before trusting part numbers and signal names, since related VAIO lines often share similar layouts.
