Lenovo Thinkpad T470p camera problem switching on and off in Windows 10

Issues

After Windows 10 performed its updates in our Lenovo Thinkpad T470p laptop, we could not use the camera. The symptoms were the following: When we tried to use the laptop camera, the camera turned on (led light is green) and after 2 seconds it turned off (led light off).

The laptop has Windows 10. In detail:

PS C:\Users\sbobos> [System.Environment]::OSVersion.Version

Major  Minor  Build  Revision
-----  -----  -----  --------
10     0      18362  0

We had searched through the web and followed multiple steps, but the camera was still not working:

  5. Google: lenovo camera not working windows 10 update

My computer looked like as it the solutions described above:

The camera permissions:

Windows 10 Camera permissions

The Lenovo Vantage configuration was:

Windows 10 Camera Lenovo Vantage configuration

Camera driver properties:

Windows 10 Camera Lenovo Vantage configuration

The actual problem:

After more than 3 hours it struck us in the head: “Why don’t we have a look in Windows log?”. While inspecting it, we stumbled upon this error:

Faulting application name: svchost.exe_FrameServer, version: 10.0.18362.1, time stamp: 0x32d6c210
Faulting module name: RsProvider.dll, version: 1.30.0.0, time stamp: 0x57ee1a06

The error appeared whenever we were trying to use the Camera.

Final solution

After searching this error at Google, I found this blog post where it gives the final solution using registry.

  1. Create a Restore Point first.
  2. Start Regedit.exe and go to the following key:

     HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media Foundation\Platform
    
  3. Create a REG_DWORD value named EnableFrameServerMode and leave the data to 0. If you’re using Windows 64-bit, make the changes here, in addition:

     HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform
    

    The above key is for 32-bit applications running on a Windows 64-bit computer. Exit the Registry Editor.

No other solution had worked for us. We hope that FrameServer is not used by another program so this trick will not cause any more issues.

I hope it helped! Happy new year 2020!
