Sony VAIO motherboard schematic for board MBX-157, carrying the internal project code RJ6 and a mainboard revision marked c with the date-like code 0508. Sony uses MBX numbers to identify its notebook mainboards, and the same number is normally printed on the PCB. The 1.64 MB PDF covers circuit pages useful for tracing power rails, checking the standby and main supplies and finding components behind a short. Confirm that the MBX number on your board matches exactly, as close numbers can differ in layout and parts.
