Schematic for a Sony VAIO motherboard numbered MBX-247, built by Quanta on its HK1 platform, supplied as a 1.02 MB PDF. Sony uses MBX numbers for its notebook boards, while the actual design here comes from Quanta. The document helps trace power rails, follow the power on sequence, check charger circuitry and identify components when repairing a dead or non booting VAIO. Confirm the MBX code on the board label before relying on it, and open the file in any PDF reader.
