Schematic for the Sony VAIO VGN-FZ25 laptop, covering motherboard MBX-165 with the MS91 design code, revision 1.0. The PDF lays out the circuit diagrams page by page, so a technician can trace power rails, follow signal paths between the chipset and peripherals, and identify the parts around a shorted line. MBX numbers are Sony's own board designations, and one MBX number can come in several sub-versions. Before relying on the drawings, compare the number and revision printed on the PCB with the ones given here.
