I have a Fujitsu Siemens Amilo S Series Si 2636 laptop with built-in webcam 1.3 MPixel and I am using Windows 7 Ultimate. I've been using it with no problems so far but when I just wanted to make a video call notice it's not working." Webcam not detected" and when I tried to look it up in search it wasn't found. What is the problem? What should I do? Please help me
