Open the webcam’s physical privacy shutter or press its camera function key (Fn plus the key showing a camera icon), then reopen the Camera app.
1. Check the camera’s physical controls
- Look directly beside the camera lens for a small sliding privacy shutter and move it fully open.
- Check the top row of the keyboard for a key showing a camera or crossed-out camera.
- Press that key once; if nothing changes, press Fn + that key.
- Open Start > Camera and check the preview.
These controls can disable the webcam and produce exactly a black image even though the Camera app opens normally.^1^
2. Check Windows 11 camera permissions
Go to Start > Settings > Privacy & security > Camera, then turn on:
- Camera access
- Let apps access your camera
- Access for the particular app you are using
- Let desktop apps access your camera if the problem occurs in a browser, Teams, Zoom, or another traditional desktop application
If Camera access is greyed out, an administrator account must enable it.^2^
Test again in Start > Camera:
- If Camera works there but remains black in another application, change that application’s video settings and select the correct camera.
- If Camera is also black, continue below.
3. Update the camera driver
- Right-click Start and select Device Manager.
- Expand Cameras or Imaging devices.
- Right-click the webcam and select Update driver.
- Select Search automatically for drivers.
- Restart Windows and test Start > Camera again.
If that does not help, download and reinstall the webcam driver supplied specifically for your PC model from the computer manufacturer’s support website.^1^
4. If the camera is missing from Device Manager
If no camera appears under Cameras, Imaging devices, or Sound, video and game controllers:
- In Device Manager, select Action > Scan for hardware changes.
- Restart the computer.
- Enter the computer’s BIOS/UEFI settings and verify that Integrated Camera is enabled.
- Install any camera and imaging-related drivers listed for the exact laptop model.
If the integrated camera remains completely absent after those checks, Windows is not detecting the device; the camera connection or module may require inspection by the manufacturer or a repair technician.^3^
