After a couple weeks of testing a Latitude 5580 with the DS1000 monitor stand dock, and having no issues, we decided to purchase a bunch of each to start deploying to our users. We've deployed six of them so far and they all display the following power warning prior during start-up.
“Alert! You have attached an undersized 60W power adapter to your system, which is less than the recommended 65W power adapter. To continue operating at peak performance, your system may also draw power from the battery. The battery charges only when the power provided by the adapter is greater than the needs of your system. Use a Dell 65W (or greater) power adapter to enable charging during peak system performance.”
Some laptops see the issue more often than others. Updating the dock firmware as well as the BIOS didn't make a difference. What seemed to have made a difference on a couple of laptops was to change the Type-C Connector Power from 7.5 watts to 15 watts in the BIOS. The issue went away on a couple of laptops, but they it came back again a few days later, so I'm not sure if it was just a coincidence or not.
The Dell info page for the DS1000 doesn't list the 5480 or 5580 in the compatibility list, however, the info page for the 5580 lists the DS1000 as one of the docks that it can use, so who knows...
It's a pretty standard setup, with just a single monitor, keyboard, mouse, Ethernet, and power connected to the dock. I also tried powering the monitor separately from the dock to no avail.
Has anyone else experienced this issue with the DS1000, or any other USB Type-C dock?
