XPS 15 9570, WD15, no longer charging, #3

I am experiencing the same problem. Laptop with WD-15 dock has worked fine and charged as expected with no issues. Today, the dock is no longer charging the laptop no matter what I do. Tried unplugging and turning on the order mentioned above but it is still not charging the laptop.

Battery charges when

  • Dock is not attached but Notebook AC Adapter is attached
  • Notebook AC Adapter is attached and the Dock is connected afterwards

Battery does not charge when

  • Only the dock is attached

No difference if dock is attached before turning on the notebook or not. All drivers/firmware bios updates have been made on both the notebook and the dock.

Hello, fwiw, I am experiencing the exact same problem...seems LOTS of people are. I have done the following and still no resolution.

  • updated all drivers
  • flashed the laptop BIOS to latest version
  • flashed WD15 BIOS to latest version
  • replaced the WD15
  • replaced the 180w power supply

So, it seems it may indeed be motherboard/usb-c related.

Due to changes made in the latest Laptop BIOS update, this is working as designed. You must have both AC power adapters connected to the Laptop and the WD15.

Hello, I am having the exact same issue and have:

  • updated all drivers
  • flashed the BIOS of the laptop
  • flashed the BIOS of the WD15 dock
  • replaced the WD15 dock
  • replaced the 180w power supply to the dock

Looking more like a laptop/motherboard/usb-c port problem.
