Hi. I'm David, and I'm happy to help you.
Are you trying to use the device's built-in camera, or an external camera?
Let's try some quick checks:
If it's the device's built-in camera, check the F1 - F12 keys on the keyboard if there is a key with a camera icon.
If you find a key with a camera icon, press the Fn key + <key with camera icon> and see if this unlocks the camera.
Also, check the camera lens to see if it has a privacy slider. If it has, open it and see if the camera will work.
If that doesn't help, tell me the model of your Lenovo laptop.
If you prefer, you can share a screenshot of your system information.
- Press "Windows + R", type
msinfo32and press Enter.
Maximize the window and use the shortcut "Windows + Shift + S" to use the screenshot tool.
Looking forward to your reply.
