It occurs from startup when connected to TBT3-UDV dock !](https://d2r1vs3d9006ap.cloudfront.net/s3_images/1691455/dellwarning_inline.JPG?1515684585)](https://d2r1vs3d9006ap.cloudfront.net/s3_images/1691455/dellwarning.JPG?1515684585)
Thanks for posting! We have already responded to the support request you sent to email@example.com, but just to cover all bases and for the benefit of anyone else following this thread I will also post a reply here.
Thank you as well for providing the screenshot of the warning message, that is most helpful. The Dell-branded power adapter included with your laptop provides 130W of power to the system, and given the Plugable dock provides 60W of power the system is notifying you of the difference.
The warning should be able to be disabled by access the BIOS and navigating to the ‘POST Behavior’ category and then selecting the ‘Adapter Warnings’ item. From there you can disable the warning, apply the change and restart. I have attached a photo from a similar system highlighting the setting in question.
Please let me know if that helps!
