Thunderbolt Configuration

If Dell BIOS is used in your system, you may find below Control options in Thunderbolt Configuration page in your BIOS Setup:

  1. Enable Thunderbolt Technology Support (Enabled by default)
    • When enabled, the Thunderbolt Technology feature and associated ports and adapters are enabled.
    • When disabled, the Thunderbolt Technology feature is disabled, and any connected Thunderbolt adapter devices are not available in preboot or within the operating system.
  2. Enable Thunderbolt Boot Support (Disabled by default)
    • When enabled, the following Thunderbolt adapter features are enabled during Preboot: Thunderbolt adapter boot support, USB device on Thunderbolt adapter support (including USB boot support). This allows Thunderbolt adapter peripheral devices and USB devices that are connected to the Thunderbolt adapter to be used during BIOS preboot. However, setting this to "Enabled" will override the Security Levels utilized within the operating system. When this setting is enabled, any Thunderbolt adapter peripherals and USB devices that are connected to the Thunderbolt adapter port before booting the system can be used in preboot. As long as the device remains connected, it continues to function within the operating system, regardless of the Security Level set in BIOS.
  3. Enable Thunderbolt Adapter Preboot Modules (Disabled by default)
    • When enabled, this setting allows PCIe devices that are connected through a Thunderbolt adapter (i.e. PCIe devices behind the Thunderbolt adapter) to execute the PCIe device’s UEFI Option ROM(s) (if present) during preboot.
    • When disabled, this setting prevents PCIe device Option ROMs from executing during preboot for PCIe devices that are connected behind the Thunderbolt adapter.
NOTE: Enabling the "Enable Thunderbolt Adapter Boot Support" or "Enable Thunderbolt Adapter Preboot Modules" options may allow devices that are connected to the Thunderbolt adapter during preboot to function in the operating system regardless of the Security Level selected in BIOS Setup. The device continues to operate in the operating system until it is disconnected. When reconnected while within the operating system, the device connects according to the Security Level and previous OS authorizations.

Thunderbolt Security

The settings below configure the Thunderbolt adapter security settings within the operating system. Security Levels are not applicable or enforced in the Preboot environment.

  • No Security: Automatically connect to devices plugged into the Thunderbolt port.
  • User Authorization: Approval is required for any new devices that are connected to the Thunderbolt port.
  • Secure Connect: The Thunderbolt adapter port allows connection to devices that have been configured with a shared key.
  • DisplayPort Only: Automatically connect to DisplayPort devices only. No Thunderbolt adapter or PCIe devices are allowed to connect.

In the BIOS of a Dell Thunderbolt-enabled laptop, you can configure the security settings of the Thunderbolt connection. You can find the configuration options in the BIOS path: System Configuration > USB / Thunderbolt Configuration.

  • No security - Allow legacy Thunderbolt devices to autoconnect – the CM auto connects a new device plugged in.
  • User Authorization - Allow User Notification devices at minimum – the CM requests connection approval from the host SW and auto-approval may be given based on the Unique ID of the connecting device.
  • Secure Connect - Allow one-time saved key devices at minimum – the CM requests connection approval from the host SW and auto-approval is only given if the host challenge to the device is acceptable.
  • DisplayPort Only - Allow DisplayPort sinks to be connected (re-driver or DP tunnel, no PCIe tunneling)

Microsoft Windows operating system includes the VGA graphics drivers only. For optimum graphics performance, it is recommended that Dell graphics drivers applicable for your laptop be installed from Dell Drivers & Downloads website under the "Video" section.

Dell Thunderbolt Docking Station WD19TB and WD19TBS is compatible with Dell laptops that has a USB-C port that supports Thunderbolt 3. The WD19TB and WD19TBS docking station works as a WD19 docking station on Dell laptops that has a USB-C port that supports DisplayPort over USB-C alternate mode.

NOTE: To learn more about what type of USB-C port is available on your laptop, see the User Guide of the laptop.

USB-C also known as USB Type-C, is an industry standard connector for transmitting both data and power on a single cable. USB-C is a common type of connector and different protocols like USB 2.0, USB 3.0, alternate modes like USB Power Delivery, DisplayPort over USB-C and Thunderbolt 3 can be implemented. For more information, see Guide to USB Type-C

Thunderbolt (previously called Light Peak) is a hardware interface that combines data, video, audio, and power in a single connection. Thunderbolt combines PCI Express (PCIe) and DisplayPort (DP) into one serial signal and also provides DC power, all in one cable. While Thunderbolt 1 and Thunderbolt 2 use the same connector as mini-DP (DisplayPort) to connect to peripherals, Thunderbolt 3 uses a USB-C connector.

To easily identify if the USB-C port supports Thunderbolt 3, look for the Thunderbolt icon next to the USB-C port.

Before using the docking station, ensure that your laptop has a USB-C port that supports DisplayPort over USB- or Thunderbolt 3 port to support the docking station.

Dell Thunderbolt Docking Station WD19TB and WD19TBS is tested for specific Dell laptops. Refer to the User Manual of the docking station to find a list of fully tested and supported Dell laptops. On non-Dell laptops, you may notice limited functionality.

Dell Thunderbolt Docking Station WD19TB and WD19TBS provides power to the laptop over USB-C cable in the following scenarios:

For Dell laptops

  • 130 W with Dell laptops and 180 W power supply

For non-Dell laptops

  • 90 W with non-Dell laptops and power supply
  • The fan is triggered by temperature. The dock fan will not rotate until the dock is hot enough to trigger a thermal threshold.
  • Conversely, if your dock is not cool enough, the fan will not stop even when you disconnect the dock from the laptop.
  • When you hear loud fan noise, it is warning you that the dock is in some kind of a hot condition. For example, the vent in the dock may be blocked or the dock is working in a high working-temperature environment (> 35C). Eliminate these abnormal conditions from the dock. If you do not eliminate the abnormal condition, in a worst-case situation, the dock shuts down through the over-temperature protection mechanism. Once this happens, please unplug the Type-C cable from the laptop and remove the dock’s power. Then, plug in the dock power to recover the dock back online.
  • This is a normal condition. First time plugging in of the dock’s AC adapter triggers the fan to rotate, but it turns off soon.
  • The dock fan is designed with two different rotate speeds. The dock works on low fan speed. If you put the dock in a heavy loading or a high working-temperature environment, the dock fan may have a chance to work at a high speed. But, this is normal and the fan will work at a low/high speed depending on the work loading.
  • The Dell Thunderbolt Docking Station WD19TB and WD19TBS can charge your mobile or power bank even without being connected to the laptop. Make sure your dock is connected to external power. The dock fan rotates automatically if the dock gets too warm. This is the normal working condition.
  • When a new device is plugged in, the USB hub driver notifies the Plug and Play (PnP) manager that a new device was detected. The PnP manager queries the hub driver for all the device's hardware IDs and then notifies the Windows OS that a new device needs to be installed. In this scenario, the user sees a hardware installation window.

  • Our Dell dock is designed to operate on AC power only, and it does not support laptop power source back (powered by laptop USB-C port). A power loss event makes all devices on the dock fail to work. Even when you restore the AC power, the dock may still not function properly because the dock still needs to negotiate proper power contract with the laptop's USB-C port and establish a laptop EC-to-dock-EC connection.
