Circuit diagram for the Sony PCG-K23 laptop on mainboard MBX-114, provided as a roughly 1 MB PDF. No revision is stated in the name, so check the label on the board. The sheets help follow the power-on sequence from adapter to CPU core supply, identify chip pinouts, and find where a rail shorts to ground. Sony's MBX prefix designates VAIO mainboards regardless of which ODM produced them. Open in any PDF viewer and use text search for net and reference names.
