PDF schematic for the Lenovo ThinkPad motherboard NM-C881, an LCFC design, with the project code RT1WL-3 in the name, archived as RAR. LCFC is the Lenovo ODM that uses NM-xxxx numbering. Technicians use these pages to follow power-on sequencing, charger and VRM circuits, enable signals and connector pinouts. Pair it with a boardview for physical locations, and check the board number on the PCB first.
