PDF for the Lenovo LCFC board NM-D461, revision 1.0; the name mentions both boardview and schematic, but this file is the PDF schematic part. NM numbering is used by LCFC for Lenovo notebooks. At 301 KB it is compact, so check that it covers the pages you need. Use it to trace power rails, follow enable and power-good signals and identify components around a short. Open it in any PDF reader, and confirm the board number and revision printed on the PCB match before relying on values.
