Hi GMMister,

Thanks for posting.  Apologies that your system is not performing as expected.

Have you run a systems diagnostics?  Please unplug all external devices except for the ac adapter, run Dell SupportAssist, make a note of any error messages encountered and post back.

Have you replaced the ac adapter or is it the original one that came with the computer?  

Here is information from the Dell Knowledge Base you may find helpful:

How to Troubleshoot AC Adapter Error Messages?

If the system is under warranty, please contact me privately. Be sure to include your personal information (name, address, telephone, email) and your computer's service tag number in your message. Thanks.

If there is no warranty, then you could contact our Out of Warranty team to get a quote for a paid service call -

Id try to look up on the internet what you did before, or just not start up with the monitor.

Hi, I have exactly the same error.

My laptop is Dell G5 15 5587 and my monitor is Dell P2419hc I'm connecting it via usb type-c and having this warning bumping each time after boot

I should press "continue" button manually each time I restart system.

Can this warning be turned off. Monitor is working fine

I have the same setup.  Dell G5 5590 with the P2419C monitor.  Getting the same error!

Can I ignore it or should I be concerned?

I am also getting the same error with my Dell G5 5590. The support team is horrible. I purchased my laptop few days back and connected it to two monitors via a docking station. I get this error that the port is not designed to accept the power while the product page says that usb-c port can transfer data (audio, video, network and power source) and also confirmed by the hardware tech support. They are making this a software issue to charge money for a new laptop which does not meet the specifications as mentioned on the product page. Dell is acting like a car dealership.

Hi sigma_dev,

Thanks for posting.

What monitors are you connecting?  What docking station are you using? Does the dock have it's own power supply?  What cables are you using?  What 

Can you connect the monitor to the laptop directly without any issues?

What wattage ac power adapter do you have?

Same issue for me.  'Warning your port does not accept power. To supply power to your system while docked attach a power adapter to your system'  

I have the same issue with my brand new G3 15 3590.  The issue happens when you plug in the Dell docking station into the turbo USB.  This happens even though I also have the laptop plugged into to the supplied AC power adapter. 

No need to ask questions about what cables, etc. This is a start up check that is failing to recognize the laptop is actually powered correctly.  It is annoying, so please offer up a fix.  You can duplicate the issue easily.

I have the same issue with my brand new G3 15 3590.  The issue happens when you plug in the Dell docking station into the docking station (VT2000 USB C Display Docking Station)

This happens even though I also have the laptop plugged into to the supplied AC power adapter. 

No need to ask questions about what cables, docking station or monitors etc. This is a start up check that is failing to recognize the laptop is actually powered correctly.  It is annoying, and hard to believe theta we are the only 10 people on earth experiencing this issue.  Dell can duplicate the issue easily but prefers to gauge you with software support fees.

plug in the Dell docking station into the docking station ? ? ?

VT2000 isn't even a Dell product 

Hi - 

I have the same issue, same annoying boot sequence error message (that I connected a charging adapter to a non-charging port). 

I have a brand new G7 7790 and a brand new dell docking station WD19TB.

The error appears even with no devices connected to the dock. Just the powered dock connected via the usb-c cable to the tb3 port of my laptop.

This is extremely annoying on each boot. There should be a setting somewhere to ignore this message. Or at least please power the laptop via the docking station tb3 connection. I know there isn't sufficient power delivered, but since you already have that hybrid power scheme, I guess it can work. Plus, I don't run my laptop on full power all the time. 85% of the time, the 100 (or 130 dell custom) w of power would be enough to run the laptop without touching the battery.

Regards,

Radu
