Answer 1

Hi! Let me help you with this issue.

Have you tried a hard reset?

Shut down the laptop completely

Click Start → Power → Shut down

Make sure it’s fully off (no lights, no fan)

Unplug everything

Remove the charger

Disconnect USB devices, mouse, keyboard, headset, HDMI, etc.

Drain residual power

Press and hold the Power button for 20–30 seconds

Don’t release it early

Reconnect power

Plug only the charger back in (nothing else)

Turn the laptop on

Press the Power button normally

Follow these steps in order on Windows 11 to troubleshoot the internal camera and the error being shown:

1. Check physical camera controls

• On the keyboard, look for a function key (F1–F12) with a camera icon and press it (often with the Fn key) to toggle the webcam on.
• Check around the camera lens for a small privacy slider/shutter and make sure it is open.

2. Verify the camera is detected

• Right-click Start > Device Manager.
• Expand Cameras (or Imaging devices) and confirm the internal camera is listed.
  • If it is missing, the device may be disabled by a hardware key (Fn + camera key) or require a driver from the PC manufacturer.

3. Test the camera in the Camera app

• Select Start > Camera.
• If the preview works here but not in other apps, adjust the camera settings in the specific app.

4. Check Windows Update and optional driver updates

• Select Start > Settings > Windows Update > Check for updates.
• If available, select Advanced options > Optional updates and install any camera or imaging device driver updates.
• Restart the PC and test the camera again using the Camera app.

5. Run the Camera troubleshooter

• Select Start > Settings > System > Troubleshoot > Other troubleshooters.
• Find Camera and select Run.
• Apply any fixes it suggests, then restart and test.

6. Reinstall or switch the camera driver

• Open Device Manager and expand Cameras.
• Right-click the internal camera > Properties > Driver tab > Uninstall Device.
• Check Delete the driver software for this device (if available) and select OK.
• In Device Manager, select Action > Scan for hardware changes to reinstall the driver, then restart and test.
• If the webcam still misbehaves and it is a USB/UVC-compatible device:
  • In Device Manager, right-click the webcam > Update driver.
  • Select Browse my computer for drivers > Let me pick from a list of available drivers on my computer.
  • Choose USB Video Device and select Next, then close and test again.

7. Check antivirus/firewall

• Some security software can block camera access. Temporarily disable or pause protection from within the antivirus app, then test the Camera app.
• Re‑enable protection immediately after testing.

If the internal camera still does not work after these steps, obtain and reinstall the latest camera driver from the PC manufacturer’s support site, or contact the device manufacturer for hardware diagnostics.
