I created an SR ( ) for this dock and its terrible performance. This dock hardly ever works on the first try. I have to plug it in and disconnect it multiple times to get it to work. 

Dell Precision 7530 bios and all drivers are up to date. TB18DC firmware is up to date. 

Usually a combination of the 2 happen, completely random and not repeatable:

1. Laptop does not charge.

2. Display one works.

3. Display two works. 

4. Nothing happens at all. 

 

I have found the best way to get the dock to work is to unplug and power down the dock, power it back up and then plug it in. It will work 50% of the time. So sometimes it takes two tries. 

 

I have taken video of this issue and have sent it to dell in my SR. If you are having similar problems, please speak up so we can let them know that this dock does not work well!
