Lenovo Yoga 740 - Docking Station Audio

2020-01-30, 22:45 PM

I am switching from a Yoga 730 to 740 machine. With my older Yoga, I used a Thinkad USB-C dock that supplied power, drove two monitors and handled audio and a couple USB connections through the USB-C port. With the new machine, the audio portion fails after the machine is up and running for a while. If I go into device manager, there is a Unknown USB device with the error logo and the message "A request for the USB device descriptor failed". I can delete the device and reboot and it doesn't come back. Play audio for a while and at some point, the sequence will reoccur. Lenovo says it is not compatible. Anyone using a USB-C dock on the 740 that can handle power, two monitors (preferably HDMI) and audio output? If so, what make/model are you using?

Hi BGSoFl,

 

Welcome to the Community Forums.

 

Would you mind sharing the part number for the dock you are using, so I can help out?

Hope this helps,

The current dock is the Lenovo ThinkPad USB-C Dock - 40A90090US. Nothing is listed in the site for the Yoga740C that looks like it has a comparable number of ports and functionality. So curious if anyone has anything comparable that is working.

Hi BGSoFl,

 

Thanks for the information.

 

I used the Lenovo Dock Finder and was not able to find a dock for both the 14 and 15 inch models of the C740.

 

I'll go and do some research and get back to you once I have anything helpful.

 

Regards,
Jack_Lenovo1

Hi Jack,

 

were you successful in the search for a suitable docking station? I'm looking for that as well.

 

Thanks
