Schematic for the Lenovo ThinkPad X230 mainboard, labelled LBD-2 with board number 11232-1, provided as a PDF inside a RAR archive. The number follows Wistron ODM numbering. The diagrams cover power rails, charging circuit, EC, CPU VRM and power sequencing, making them the starting point for no-power and no-boot diagnosis. Pair it with the X230 boardview to locate parts quickly. Confirm the board number on the PCB matches before trusting the drawings.
