Sony VAIO schematic for board MBX-250, designed by Wistron under its Z40HR project name, as a 2.46 MB PDF. Sony labels its laptop boards with MBX numbers while the ODM project code appears on the drawings, and the MBX code on the PCB should match. The schematic shows the power sequence, rail names, charging and EC circuits, letting a technician measure the right points, trace signals and identify components on a shorted line. It opens in any PDF reader and searching for net names helps navigation.
