PDF schematic for the Lenovo ThinkPad E470, built on LCFC motherboard NM-A821 at revision 2.0. LCFC is the Lenovo-owned board maker behind the NM- numbering used on many ThinkPad and IdeaPad boards. The diagrams show the power architecture, charger and regulator circuits, the power-on sequence and connections between the CPU, memory and peripherals. Technicians use them to trace missing rails, identify parts on a short and check signal routing. Confirm that NM-A821 and the revision on your PCB match before relying on component values.
