Mainboard layout for LCFC board NM-B452, revision R02, discrete-graphics (DIS) version, as a 6.78 MB .tvw file for Lenovo hardware. Being a DIS board, it covers the dedicated GPU section along with the rest of the system. In a TVW-capable viewer you can search reference designators, inspect pin nets, find measurement points for VRM outputs and follow signals between chips while looking for a short or missing rail. Compare the board number and rev 02 printed on your PCB, as the sister NM-B453 and UMA variants differ.
