So my webcam stop working.. in the last month I see the blue led turning on and off when I was using the notebook .. and now the webcam just stop working at all.

The blue led doesn't turn on when the notebook is power on. The Device Manager can't find a Image Device. The Dell webcam manager doesn't find too.

I try to reconnect the cable under the keyboard but without luck, the cam still don't work. Anyone have see this? Any tips?
