PDF schematic for the LCFC NS-C821 IO daughterboard at revision 1.0, a small Lenovo sub-board that pairs with the NM-C821 main board family. IO boards typically carry USB ports, audio jacks, card readers or power buttons, and this 723 KB diagram shows how those signals and supply lines reach the main board connector. Use it to trace dead ports, check fuses and test continuity through the interconnect cable. It opens in any PDF viewer. Confirm the NS-C821 marking and revision on the physical board first.
