Schematic in PDF form for the LCFC NM-A981 motherboard, drawn for the CG413 and CG513 layouts in the discrete-graphics version, packed in a 3.13 MB RAR. NM-A numbering is the pattern Lenovo's LCFC unit uses, and the boards show up in Lenovo laptops. Use the diagrams to trace power rails, the dedicated GPU supply and signal paths, and to find the parts behind a short circuit. Check that the NM-A981 marking on the PCB matches and that your board actually carries the discrete GPU before relying on GPU sheets.
