LCFC schematic for the Lenovo board NM-A681 with project code CG510, preliminary revision r0.2, in a 1.39 MB PDF. LCFC project codes like CG510 pair with an NM- board number, which helps match the document to the right laptop family. Because it is a 0.2 engineering revision, production boards may show changed parts, so verify against the PCB. It serves for tracing rails, finding components and test points, and working through power sequencing on a dead board.
