Fix 1 — Verify Dock USB-C Port Compatibility Check first
The ThinkPad T16 Gen 2 AMD has USB-C ports that support different standards depending on the port. The left-side USB-C port supports Thunderbolt 4 (on some AMD configs) or USB4. The right USB-C may be USB 3.2 only without DisplayPort Alt Mode. Connect the dock to the left USB-C port. Check the dock specifications — a Thunderbolt-only dock will not work on a USB 3.2-only port.
Fix 2 — Update USB-C / Thunderbolt Driver
Visit Lenovo Support and download the AMD USB Hub driver and AMD Platform drivers for the ThinkPad T16 Gen 2. The AMD Ryzen 7 7780U uses AMD USB4 controllers that require specific drivers for dock enumeration, separate from the Intel Thunderbolt driver used on Intel ThinkPad models.
Fix 3 — Update Dock Firmware
Connect the Lenovo dock to the ThinkPad T16 and open Lenovo Dock Manager (available from Lenovo Support). Allow it to check for and install firmware updates for the dock. Dock firmware updates often include AMD USB4 host controller compatibility patches that resolve detection failures on AMD-platform ThinkPads.
Fix 4 — Test with Direct USB-C Connection
Connect a known-working USB-C device (USB drive, monitor with USB-C) directly to the same port as the dock. If direct USB-C devices work but the dock does not, the dock itself has a compatibility or power issue with this port. Try the dock on the alternate USB-C port or connect the dock with its AC adapter plugged in.

Common Questions
Which docks are officially compatible with the ThinkPad T16 Gen 2 AMD?
Lenovo Universal USB-C Dock, Lenovo USB-C Dock Gen 2, and Lenovo Universal Thunderbolt 4 Dock (on TB4-capable AMD configs). Check the Lenovo dock compatibility list for your specific T16 model number.
Does the ThinkPad T16 Gen 2 AMD support DisplayPort over USB-C?
Yes, on USB-C ports with DisplayPort Alt Mode support. Check your specific model on Lenovo Support — the main left USB-C port typically supports DP Alt Mode, the right may not.
Why does the dock work once but not on reconnection?
USB Selective Suspend or AMD power gating can put the USB4 controller into a low-power state that does not correctly reinitialize when the dock is reconnected. Disable USB Selective Suspend in Power Options.
Can I use a third-party Thunderbolt dock with the ThinkPad T16 Gen 2 AMD?
On TB4-capable AMD configurations, yes. USB-C-only docks work on all USB-C ports with DisplayPort Alt Mode support. Thunderbolt-only docks require the TB4 port. Verify port capabilities before purchasing a third-party dock.

Why is the Lenovo ThinkPad T16 Gen 2 AMD dock not being detected?
Common causes include connecting the dock to a USB-C port without DisplayPort Alt Mode or Thunderbolt support, outdated AMD USB Hub driver, dock firmware incompatible with AMD USB4 controllers, or USB Selective Suspend powering off the USB4 controller. Install the AMD USB Hub driver from Lenovo Support and update the dock firmware.
What USB-C standard does the Lenovo ThinkPad T16 Gen 2 AMD support?
The ThinkPad T16 Gen 2 AMD with Ryzen 7 7780U supports USB4 Gen 2×2 (40 Gbps) on its primary USB-C port, with DisplayPort Alt Mode and USB Power Delivery up to 100W. Some configurations include Thunderbolt 4. The secondary USB-C port may be limited to USB 3.2 Gen 2.
Is the Lenovo ThinkPad T16 Gen 2 AMD compatible with Lenovo Thunderbolt docks?
On configurations with Thunderbolt 4, yes. On configurations with USB4 only, Thunderbolt docks may work at reduced capability (USB4 backward compatibility) or may not work at all depending on the dock. Use Lenovo USB-C docks for guaranteed compatibility with the AMD platform.
Does the ThinkPad T16 Gen 2 AMD support multiple external monitors via dock?
Yes. Using a USB-C or Thunderbolt dock with multiple DisplayPort or HDMI outputs, the T16 Gen 2 AMD supports up to two external displays. The AMD Radeon 780M iGPU handles multi-monitor output through the USB-C dock connection. Resolution support depends on the dock and display specifications.
