Quanta-made motherboard schematic for project GD1B, which carries the Sony board number MBX-177A, revision 2A, in a 1.63 MB PDF. Sony laptops of this kind were often produced by Quanta, so the document pairs the ODM project code with the Sony MBX identifier. Technicians use it to follow power rails, check the startup sequence, identify components around a failed circuit and read test points and connector pinouts. Make sure the board label and revision on the PCB match MBX-177A rev 2A before trusting values.
