Symptoms

A message appears during POST if a Dell Thunderbolt docking station is connected to a non-Thunderbolt USB Type-C port (See Figure.1) on any commercial Dell laptop. (WD19TB, WD19TBS, or WD22TB4.) Pressing the F1 key allows the laptop to boot normally. (See figure.2)

Note: The Dell Thunderbolt Docking Station (WD19TB, WD19TBS, or WD22TB4) functions on devices with a USB Type-C port that supports DisplayPort over USB-C or Thunderbolt. When connected to a DisplayPort over USB Type-C port, the Thunderbolt dock functions as a WD19 or WD19S dock. Verify that your computer supports DisplayPort over USB Type-C, Thunderbolt 3, or Thunderbolt 4.

Non-Thunderbolt Type-C port

(Figure.1 Non-Thunderbolt USB Type-C port)

Error Message before and after August 2019

(Figure.2 Error Message The Docking Station you have connected cannot provide full functionality while connected to the current port. If you have a Thunderbolt port, attach the docking station to that port for full functionality.)

The error message informs you that you should not expect Thunderbolt 3 connectivity from the dock. This is because it is not attached to a Thunderbolt port on the computer which it is attached to.

Cause

A BIOS update resolves this.

Resolution

Updating the latest BIOS version on the computer helps to resolve the issue. To download and install the latest BIOS:

Warning: Dell Technologies recommends disconnecting any external devices like external hard disk drives, printers, scanners before updating the BIOS.
 
Warning: Dell laptops must have the battery installed and charged to at least 10% before you begin the BIOS update. Dell Technologies recommends connecting the laptop to AC power before proceeding with the update process.
 
Note: To learn more about updating the BIOS on a Dell computer, see the Dell Knowledge Base article: Dell BIOS Updates
  1. Browse to the Dell Drivers & Downloads Product Support Drivers Page

  2. Ensure that your computer model type is correct

  3. Select the Operating System

  4. Under Category, select BIOS

  5. Locate the latest System BIOS

  6. Click Download and save the file to your computer

  7. Open File Explorer and browse to the location where the downloaded file is saved

  8. Double-click the BIOS setup file and follow the on-screen instructions to complete the installation process

You can skip this message by pressing the F7 key or by disabling USB-C Dock warning messages in the BIOS. However, a second message is showing in Dell SupportAssist. It can only be adjusted with the setting continue on Warnings and Errors, but the error is shown on the next boot. (See figure.3)
