Instructions

Dell Command Update and the TB16 or TB18DC Docking Station

Note: Dell Command Update (DCU) supports: OptiPlex, Tablet, Precision, XPS, and Latitude laptop models that are running the following Windows Operating Systems: Windows XP, Vista (32/64-bit), Windows 7 (32/64-bit), Windows 8 (32/64-bit), Windows 8.1 (32/64-bit), and Windows 10

The Dell Precision Dual USB-C Thunderbolt Dock: TB18DC is ONLY compatible with the Precision 7530 or 7730 Mobile Workstation. If you are experiencing power issues during these steps and are using a surge protector. Disconnect the system from the surge protector, connect to a power outlet directly, and continue.

First, download the latest version of the Dell Command Update (DCU) tool on Dell Support and follow the two-part process to verify that all the updates for the BIOS, Drivers, and Firmware have been installed.

Warning: Ensure the TB16 or TB18DC is disconnected from the system.
  1. Open the DCU tool and on the lower right side of the screen, click the link to run the "Advanced Driver Recovery" option. Allow this to complete and restart the system.
  2. Reopen the DCU tool and this time run a "Check" using the blue button above the "Advanced Driver Restore" option.
  3. Now, connect the TB16 with all monitors and peripherals connected to the dock.
    Note: Check the Thunderbolt cable light, it should turn on when connected to the system.
  4. Go to Dell Support, find the system with the dock connected and run the check for drivers and install any updates.

By following this process, the tool first verifies that all base drivers and firmware are installed. This cleans up any discrepancies in Device Manager. This paves the way for the second process and ensures that it is as accurate as possible in finding and updating the BIOS, Drivers, and firmware in the system. Then by going online, get the latest updates to the system that have been recently posted online but not added to DCU.
