So the Dell Precision 7520/7530 has a USB-C port. Which you can plug a Dell USB-C dock into it.
And it works well. Until you close the laptop lid and the laptop decides to Hibernate.
“It’s faulty”, I say to the Dell Engineer.
Some thinking later, the Dell Engineer responds
The Precision laptop requires 180W of power to charge the laptop.
The USB-C output is at a maximum, of 100 watts. Notice how the battery icon shows that it’s not charging?
The solution, in the words of Dell:
“Systems docked via USB 3.0 Type-A connections or systems that require more than 65 watts power input to power the system and charge the battery will require a separate AC power adapter to power the system and charge the battery.”
Dell Universal Dock (D6000) system charging limitations
Plugging the USB-C dock into the USB-C socket will still allow you to use the dock.
Just not charge from it.
