Schematic package for a Sony VAIO mainboard numbered MBX-247, which the name says was designed by Quanta under the HK1 project code, supplied as PDF inside a RAR archive. Sony MBX numbers are Sony's own board identifiers, while the Quanta project code tells you which ODM drawing set applies. Technicians use these diagrams to follow power rails, check the charging and standby circuits and find components feeding a short. Confirm the MBX number on the PCB label before trusting values, as related Sony boards share similar layouts.
