Troubleshoot T440s webcam

 

My T440s webcam stopped working. I'd appreciate troubleshooting suggestions. It seems to have failed after the Win 10 1607 update, but I can't pin down the timeline to be sure.

 

Symptoms:

  • Skype and Camera app both show camera icon with diagonal line instead of image:
  • IconNoImage.jpg.
  • Green light comes on when software tries to use camera
  • Windows registry trick to fix much publicized USB webcam issues with 1607 does not help.

Details:

  • Windows 10, update 1607.
  • Device Manager shows Integrated Camera "SunPlusIT", "working properly".
  • Driver 2016-03-07, ver 3.5.7.25.  Windows update says that is the latest.

For those interested I've pasted the events logged from this device below, all of which are timestamped to the time that the 1607 update was done.

 

Thanks for any help.

  • Device USB\VID_04F2&PID_B39A&MI_00\6&86b9249&0&0000 requires further installation.

Re: Troubleshoot T440s webcam

Nothing like posting a question to make me think of an answer. The older driver from Lenovo solved the problem:

Package   Sunplus  / Realtek           Rev.  Issue Date
  --------  -------------------------    ----  ----------
  1.0.0.10  3.4.7.36 / 6.2.9200.10252    03    2015/09/11
