PDF schematic for the Sony VAIO VPCEL series on the MBX-252 board, which the name links to Foxconn design projects M960 and M970_H, so Foxconn appears to be the ODM behind this Sony-numbered board. Packed in a rar under 1 MB, it lets a technician trace power rails, check signal paths and find the parts involved in a short or no-power fault. Open it in any PDF reader and confirm the board number and revision on the PCB before relying on the values.
