Laptop schematic collection for the Sony VAIO VGN-FS series, with the xxxx standing in for the individual model variants, in a 1.15 MB RAR. The name gives no board number or revision. The FS line used more than one main board, including MBX-130 and MBX-143, so check which MBX code your PCB carries and compare it with the title block inside. Once confirmed, use the drawings to trace power rails, locate test points and isolate shorted components.
