Thunderbolt Dock is charging but Monitors will not work

2018-02-20, 20:36 PM

I have narrowed the issue down to a software issue.  I have tried resetting the dock, the computer, updated to the newest driver as well as even replacing the dock itself.  I had an extra and thought the dock ports might just be dead but the new dock doesnt work either. 

 

I have also tried both ports on the PC in order to rule that out as well.  Does anyone have suggestions? 

 

Thank you in advance!!

In case anyone else has this issue, I did end up resolving it.

The Display Port cable I was using was not functioning correct to the point where it stopped the entire dock from pushing any screens. Replacing the cable fixed the issue.

I assume you mean the Thunderbolt 3 Dock.

 

Have you applied the dock's firmware as well as installing the driver?

Unfortunately this did not resolve the issue. I was unable to do the firmware update, I assume this was because the device was not recognized although, like I said it is charging and the device light turns white when plugging in the laptop.

Re:Thunderbolt Dock is charging but Monitors will not work

I had a client that has a ThinkPad X1 Yoga 3rd Gen connected to a Lenovo Thunderbolt 3 dock and it was experiencing the exact same issue of charging working, but nothing else on the dock. In this case, it turned out to be that the battery in the ThinkPad had swelled and was putting pressure on the motherboard. Removing the swollen battery immediately solved the issue. Just thought I'd mention it in case anyone comes across this thread while researching the issue in the future.
