Lenovo ThinkPad L412 motherboard schematic for board DA0GC9MB8D0, revision D, supplied as a 1.12 MB PDF. The DA0...MB... number format belongs to Quanta, the ODM that manufactured this board. A technician can follow power rails, the power-on sequence and signal paths, and use the reference designators to find parts linked to a short or missing voltage. Open it in any PDF viewer and make sure the revision on your PCB matches, because component values and placement can change between revisions.
