Sony VAIO VPCEL schematic for the MBX-252 motherboard, a board that the file name indicates was built by Foxconn, with the codes M960 and M970 also listed. Sony assigns its own MBX numbers even when an outside manufacturer such as Foxconn produces the board. The roughly 1010 KB PDF is used to follow power rails, the charging and power-on circuits and signal paths between major chips. Confirm the MBX-252 sticker and Foxconn markings on the PCB, then open the document in any PDF reader and search nets by name.
