PDF schematic for the Lenovo ThinkPad L13, project Lar-1, on the Wistron 18834-1M motherboard, packed in RAR. Wistron builds many ThinkPad boards and numbers them in this five-digit-plus-suffix pattern. Use the diagram to follow power rails, the power-on sequence, charger and EC signals, and the pinouts of key ICs during board-level repair. Any PDF reader opens it. Check that the board number and suffix printed on the PCB match, because related variants such as 18834-1N exist.
