I have an Inspiron 11 3000 running Windows 10. The built-in webcam is not working. It didn't show up under Device Manager; when I went to Show Hidden Devices I saw it but it was greyed out. Clicking on Properties got me the following message: "Currently, this hardware device is not connected to the computer. (Code 45) To fix this problem, reconnect this hardware device to the computer."

This is not an external webcam that I can unplug and plug back in, it's built into the laptop itself! What on earth does this mean and how can I do what it's asking?

(Yes, I have already tried searching for driver updates and restarting the computer.)
