Hi!
I have the same problem and the way to fix it is:
- Open Device Administrator
- Find the line of the integrated camera
- Right click and select Properties
- Select Controller tab
- Click on "revert to previous controller" (o something like this, my Windows version is in Spanish)
Apparently there is an incompatibility between the Lenovo driver and the last Windows version
If this doesn't works try first to unistall the device (right click on Integrated Camera in the Device Administrator and select unistall device), reboot. You can find after reboot that the camera works fine, but about 5-10 minutes doesn't works. Then you can try the solution above.
I hope this fix tour problem.
Regards,
Carlos
