Dear Alan Dennes,
I understand how inconvenient this is, especially when Windows Hello facial recognition was previously working and you now need to sign in manually each time.
To help narrow down, could you please let us know the following:
- Did the issue start after a recent Windows Update or Lenovo driver / firmware update?
- Does the built-in Camera app open and show video normally?
- Is there any privacy shutter / camera cover on the Lenovo Yoga, and is it fully open during sign-in?
- Does Windows Hello show any specific message?
- Are you able to sign in with your PIN and then go to Settings > Accounts > Sign-in options > Facial recognition (Windows Hello) to see whether “Improve recognition” or “Set up” is available?
In the meantime, you may try the following steps:
- Make sure the camera is fully visible during sign-in
- If your Lenovo has a physical privacy shutter or any camera cover, please make sure it is completely open.
- Test in a brighter environment
- Please try signing in in a well-lit room, facing the screen directly.
- Use Improve recognition or remove and set up Face again
- Please sign in with your PIN first, then go to: Settings > Accounts > Sign-in options > Facial recognition (Windows Hello)
- Try Improve recognition first
- If needed, remove Face recognition and set it up again afterward
- Confirm the camera works in Windows
- Open the Camera app and check whether the camera preview opens correctly.
- Run the Windows camera troubleshooter
- Please using the Camera troubleshooter in the Get Help app for Windows 11 camera-related issues.
- Check Windows Update and Lenovo updates
- Please check for Windows Update, Optional driver updates and Lenovo driver / firmware / BIOS updates for your exact Yoga model
While my initial response may not fully resolve the issue, I truly appreciate your cooperation as we work together toward identifying the most effective solution. Thank you so much for your understanding.
I hope these steps help restore Windows Hello facial recognition on your Lenovo Yoga and make sign-in more reliable again. Wishing you a smooth experience with your Windows 11 device and a quick resolution to this issue.
