Schematic for a Sony VAIO laptop motherboard numbered MBX-143, tagged with the MS04 project code and drawn at revision 1.0. Sony assigns MBX numbers to its notebook boards regardless of which contract manufacturer built them. Open the 1.48 MB PDF in any reader to trace power rails, check signal connections between the chipset, memory and connectors, and find components linked to a fault. Make sure the MBX number and revision on the PCB match this drawing before replacing parts based on it.
