Sony VAIO VPCY2 schematic for the MBX-229 motherboard, a 2.91 MB PDF with no revision stated in the name. Use it to follow the power path from the adapter input through the charger and system regulators, check enable signals, and identify components on a shorted rail. MBX-229 is Sony's designation for a board that Wistron built under its own numbering. Read the title block to see which revision this copy documents, and match it against the PCB markings before relying on values.
