Circuit diagram set in PDF format for Sony VAIO VGN-FS series notebooks, drawn for the MBX-143 mainboard with the MS03 project code. Use it to check the power-on sequence, measure the voltage regulators against their expected outputs, and work out which components sit on a rail that reads shorted to ground. Any PDF viewer opens it, and text search helps locate net names quickly. Sony fitted several MBX boards across the FS line, so confirm the board silkscreen reads MBX-143 before treating these pages as a reference.
