TBT3-UDZ not charging Yoga 730

#1

Hello,

I’ve been having issues with the TBT3-UDZ docking station charging my lenovo yoga 730. It starts to charge and then my screens blink and it stops charging.

Thanks for the help

Hello Gus,

Thank you for reaching out on the forums!

I am sorry to hear that you are running into issues with your TBT3-UDZ, but I would be happy to help diagnose the issue here.

First, can you confirm that you are trying to connect to your laptop using the included Thunderbolt 3 cable that came with your dock? We’ve seen issues arise when a third party cable is used.

Next, some steps we’ll want to take are to perform a power-cycle of the unit to reset its internal hub chipset. We’ve seen that this can often restore the dock back to a working state when one or more of its functions are not quite working. To do this, please follow these steps:

  1. Disconnect all USB peripherals and displays connected to the dock
  2. Disconnect the docking station from host machine, then disconnect the power adapter from power
  3. Leave unplugged for 1 minute for power to dissipate
  4. Connect docking station initially into power only
  5. Connect docking station to host machine, then connect USB peripherals and displays, then test for functionality

Please let me know if this helps at all.

Lastly, can you confirm that this issue is present no matter which USB-C port you connect the dock to on your laptop?

Thank you,

Evan

Hi
I am using the thunderbolt 3 cord that came with the dock.

I followed the steps and it did the same thing it started charging then it blinked and it stopped charging. I then followed the steps again and used the 2nd port on the laptop and it did the same. So its still not charging.
