Discrete-graphics edition of the LCFC NM-A982 schematic, CG413 project, packaged as a PDF in a 3.12 MB RAR archive. Unlike the UMA drawings, this set includes the dedicated GPU, its VRAM and power stages, which explains the larger file. LCFC builds Lenovo laptops and uses NM-xxxx board numbers. Technicians use it to diagnose GPU core shorts, missing VRAM supply or switching signals between graphics. Confirm that a discrete GPU is fitted on your board and the PCB number matches.
