Schematic for the Lenovo motherboard NM-B244, revision 1.0, used by the DG42A and DG52A platform codes, packed as a PDF inside a RAR archive. The NM-xxxx numbering follows the LCFC pattern, the Lenovo-owned ODM that designs many IdeaPad and ThinkPad boards. Open the PDF in any reader to trace power rails, follow enable and power-good signals, and look up component values around a short. Confirm that the board number and revision printed on the PCB match before trusting part references.
