Lenovo ThinkPad T480s schematic for the LCFC NM-B471 mainboard, supplied as a sizeable 9.88 MB PDF. LCFC is Lenovo's own manufacturing arm and its NM-xxxx board codes appear on many ThinkPad and IdeaPad models. A technician uses these drawings to trace power rails, follow the Type-C charging path, locate the EC and SPI flash, and identify test points when hunting a short. Confirm NM-B471 is printed on the board before relying on the component values.
