Questions about this item

Which motherboard part number must my Latitude E5400 already have for this C959C IO board to connect properly?

The C959C IO board is designed only for motherboards carrying part number C949C with integrated Intel video; other E5400 motherboards will not accept it.

Will the two USB ports and audio jacks on this C959C board function the same as the original right-side IO panel on my E5400?

Yes, this genuine Dell replacement provides identical USB and audio connectivity because it mirrors the original C959C layout for C949C motherboards.

After installing the C959C board, how can I confirm the DC power jack and SIM slot are working correctly?

The laptop should charge normally when the adapter is plugged into the jack, and a recognised SIM card should appear in the network manager once the board is seated and the system boots.
