Hello Lenovo Users!
Your computer is equipped with a really nice security feature. This allows you to physically disconnect the camera and microphone from the computer and also cover the camera lens.
Lenovo calls this feature "ThinkShutter" and it may not have impacted you before our e-Learning journey.
If your camera seems to be on, but is not usable please try the following procedure to open the shutter.
The YouTube video below shows you how to open and close the "ThinkShutter" on your computer so that the camera is usable for Hangouts Meet, Wevideo, etc.
