Built in WebCam Problem Solve

I have a problem on built webcam after upgrading the old Windows to Windows7. The Webcam is "Not Detected Hardware" or Uninstalled. As we know Windows 7 has all drivers and it can auto update any driver available.

Most Laptop with this trouble are:

Asus
Acer
Samsung
Neo

As you see no Webcam is detected except for "Base System Device " (system device PCI or Card reader)

Device Manager....

On Device and Printers..

Like a built in WiFi device , built in WebCam need a hardware enabling device. The default key is Fn + F10 ,after pressing these key you will notice your webcam "Lights On" or Try any Fn+ combo key F1 to F12

NOTE: Look for Product Manual on How to Enable WebCam . Now its working vice Manager and Device and Printers.
