Follow these steps in order on the Windows 11 Lenovo Yoga Pro 9i:
- Test the camera in the built‑in Camera app
- Select Start > Camera.
- Check if the preview works.
- If the camera works here but not in other apps, the issue is with those apps’ settings.
- Check for Windows and driver updates
- Select Start > Settings > Windows Update > Check for updates.
- If available, select Advanced options > Optional updates and install any camera or system driver updates.
- Restart the PC: Start > Power > Restart (do not just wake from sleep).
- Test again with the Camera app.
- Run the Camera troubleshooter
- Select Start > Settings > System.
- Select Troubleshoot > Other troubleshooters.
- Find Camera and select Run.
- Apply any fixes it suggests and restart if prompted.
- Check antivirus or security software
- Open the antivirus/security suite installed on the device.
- Look for any webcam/camera protection or privacy blocking features.
- Temporarily disable those protections and test the Camera app again.
- If the camera shows black screen or no video
- Open Start > Device Manager.
- Expand Cameras and locate the Yoga’s camera.
- Right‑click it > Update driver > Search automatically for drivers.
- After update completes, restart the PC and test again.
If the camera still does not switch on after these steps, test whether it works in any app at all (Camera app, Teams, etc.). If it fails everywhere even after driver and Windows updates, this may indicate a Lenovo‑specific driver/firmware issue and the next step is to install the latest camera drivers from Lenovo’s support site for the Yoga Pro 9i.
