Thinkpad T420 Integrated Camera § Windows 8.1 ?

Hi Lenovo,

 

The Integrated Camera on my Lenovo Thinkpad T420 don't work on Widnows 8.1.

In device manager I see: Unknown USB Device (Device Descriptor Request Failed)

 

I already have installed camera drivers for Windows 7, Lenovo System Update, Lenovo Settings Dependency Package.

 

Any other suggestion?

Hi Imarh,

Welcome to Lenovo Community!

As per the query we understood that you are facing issue with Camera on your ThinkPad T420.

Right now your system is installed with Windows 7 or Windows 8.1?

Can you able to see imaging device in Device manager; is there any yellow mark in that?
If it is Windows 8.1 and it is showing Unknown USB Device in Device Manager, please provide the hardware ID.

Hope to hear back soon!

Best regards,

Hemanth Kumar

Hi Imarh,

 

Check updating the system BIOS once, if the issue still persists then you have to perform clean installation of windows 8.1.

 

Hope this helps.
