Some Systems with USB Type-C Port Lack a Thunderbolt 3 Controller



Summary: Latitude 5175, 5179, 5280, 5480 (U/H UMA), 5580 (U/H UMA), 5285 & 5289 portable systems with USB Type-C ports that lack a Thunderbolt 3 controller.


System Will Not Work With a Thunderbolt 3 Device

You may encounter an issue where a Dell Latitude system with a USB Type-C port will not support a connection to a Thunderbolt 3 device (such as a Dell Thunderbolt Dock (TB16). This is a result of either:

  • The system does not meet the hardware requirements for Thunderbolt 3
  • The system has the capability but was not ordered with an OPTIONAL Thunderbolt 3 controller



Ensure That Your System is Equipped With a Thunderbolt 3 Controller

Note: If the system was not ordered with the Thunderbolt 3 options, it cannot be added at a later time.

While many Dell systems are equipped with a USB Type-C port, many of these systems do not have the optional Thunderbolt 3 controller. These systems will have the USB Type-C port which can be used with Thunderbolt 3 on systems that are so equipped, but USB Type-C is the default port (Without Thunderbolt) for several systems.

Types of USB Type-C ports:

  • Power/Charge Battery
  • Data use only (select systems only)
  • DisplayPort over USB
  • Thunderbolt 3 device support (Optional on many systems, Standard on select systems)

These systems have USB Type-C but DO NOT HAVE Thunderbolt 3 capability:

  • Latitude 5175 2-in-1
  • Latitude 5179 2-in-1
  • Latitude 5280
  • Latitude 5290
  • Latitude 5480 (U or H processor and Unified Memory Architecture (UMA) integrated graphics)
  • Latitude 5580 (U or H processor and Unified Memory Architecture (UMA) integrated graphics)
  • Latitude 5490
  • Latitude 5590
  • Latitude 5285
  • Latitude 5289

DisplayPort over USB Type-C ONLY:

  • Vostro 13-5390
  • Vostro 13-5391
  • Vostro 14-5490
  • Vostro 15-5590
  • Vostro 15-5581

Here is an example of a USB Type-C system order SKU: 338-BKXK Intel HD Graphics 620 with Displayport over USB Type-C with Core i5 vPro

These systems are compatible with the Dell USB Type-C Dock (WD15)

Systems that have optional Thunderbolt 3 capability will have a USB/Thunderbolt configuration option listed in the BIOS regardless of having a Thunderbolt 3 option installed.

If the system DOES NOT have Thunderbolt 3 capability, the thunderbolt options will be grayed out and cannot be selected in the BIOS. (See figure 1.)
