Hello, I have a Lenovo Y550 ideapad and Windows 7 x64.

A few days ago, my internal webcam randomly stopped working.

Here is what I have tried so far:

1. Pressing Fn+Esc does not work. It only gives a message: Warning! There is no camera installed on this computer.

2. I re-installed the Power Management driver as suggested by some or the forums, and this did not help.

3. I tried to uninstall and reinstall the Camera device driver, but this failed and gave the message: Warning! No Matched Device Driver.

4. The webcam is not shown in the Device Manager, so I cannot remove and re-install it.

5. http://www.testwebcam.com/ does not show a device.

It seems as though the webcam is disconnected and not even seen by the OS. Does anyone have any suggestions? I'm completely out of ideas. Thanks in advance!

after un-installing drivers, restart your computer and start in safe mode. then try to re-install drivers.

by the way, is there any unknown/non-installed device under device management?
