I have a Dell Latitude E6520.. I was using my integrated webcam on Skype, until suddenly the screen went black, and the LED light next to it, is no longer on, yet it is still detected.. I tried SO many things among which:

• I uninstalled the webcam from the device manager and restarted
• I uninstalled all the USB devices from the device manager and restarted
• I ran a System Restore
• I cleaned registry and all temporary files
• I exposed the camera to strong light
• I installed Dell cam central

All of this and still no luck..
