WD15 & 5x80 Latitude

Can you confirm you've got a 180W power supply connected to the WD15?  The WD15 is sold with 130W and 180W power supplies, but 180W is the minimum power supply when using a Latitude 5x80 according to the WD15 FAQ here.  For the power button, the manual does suggest that it's just a Sleep/Wake button, which does surprise me. I'm wondering if that might just be a limitation of the USB-C spec, because the T1B16 Thunderbolt Dock's power button does work as a full power button, although I haven't confirmed that.

Thx for answer. Yes i use 180W , tried also with 130W and 210W, same issue.

Without WD15, directly on notebook seems to be fine.

If I am in the BIOS and exchange the power supplies while you hang on the WD15, always 90W is displayed. Dell says although usb-c should be supported only 100w should be seen 130w?

The USB Power Delivery spec supports up to 100W, and the WD15 is capable of supplying up to 130W to a connected system (I guess they're stretching the voltage and/or amperage a bit), but that doesn't mean that every source needs to provide that much power or that every device needs to accept that much. I don't have a 5480 to test with, but it might only accept 90W over USB-C.  However, it definitely should NOT be throwing a warning about inadequate power when connected to a WD15 driven by a 180W power supply.  Assuming you've seen this with multiple AC adapters connected to the dock, that sounds like it might be a hardware issue with the dock.  There is a firmware update for that dock that you can try if you haven't already, though.

Dear, the firmware is already up to date & tried also another wd15 with another 5x80, same issue

After repeated tests we have found the problem:

If the Dock WD15 loses power overnight, you will not have any more voltage, The Power Button does not work on the WD15 when the notebook is connected via USB-C, the LED on the USB-C cable is off. If I start the notebook via the power button on the notebook comes exactly this error message. It recognizes what is connected to USB-C, but does not provide the desired power / watts.

When I then disconnect the USB-C from the notebook and connect it again, it works again, LED on the USB-C lights up and the notebook can be started via the WD15 Power Button.

The problem exists with current firmware (DellDockingStationFwUp_1.0.0.8_20161220_WD15.exe) as well as at a new unpacked WD15 (assumes here is still an older firmware installed?)

The problem is exactly adjustable, we ask for fast troubleshooting, please forward to firmware department and fix it a.s.a.p.

Thx in advance

I have the same issue.  Latitude 5580 with a WD15 dock.  Installed current firmware and received the power message at boot.  It is now a month later.  I wonder if a real fix is immanent.

Exactly, but an official opinion can be expected, right ? I think sooner or later, everyone will stumble on this problem.

It is now November and we also have the same issue with several of our WD15 docking stations and 5480 laptops. Using 180W power supplies, using Dell Command|Update so all of updates for the laptop and the docking stations have been performed. Have there been any updates as to a fix for this issue?

This is the answer from DELL:

Unfortunately, I have to tell you that this is a normal behavior of this configuration and thus can not be assessed as a misconduct. Whether there will be a change with future firmware customizations is currently unknown.

I forwarded your request for an official statement / statement.

Having the same issue.  Hoping Dell addresses this.
