135 W ThinkPad dock for select 480 and 580 models
This Lenovo 40AJ0135US docking station delivers 135 W of power to compatible ThinkPad laptops including the T480, T580, P580p, X1 Carbon Gen 6 and X280. It connects through a single proprietary cable and adds video, network and USB expansion at the desk. The unit ships new with its AC adapter included.
Office users needing triple-display and legacy ports
Workers who want to drive up to three external monitors through two DisplayPort 1.4 outputs and one HDMI 2.0 port, plus a VGA connection for older projectors, will find the port mix useful. Gigabit Ethernet, a combo audio jack, one USB 3.1 Gen2 Type-A port with always-on charging and two USB-C 10 Gbps ports round out the connectivity. Buyers whose laptops are not on the supported model list should look elsewhere.
135 W power rating matches the supplied adapter
The dock’s 135 W DC input aligns with the bundled AC adapter, so the single-cable connection can charge the host laptop while driving peripherals. If a ThinkPad requires more than 135 W, this station will not provide sufficient power.

Questions about this item
How do I connect the 135 W Lenovo ThinkPad Dock 40AJ0135US to my ThinkPad X1 Carbon Gen 6, and which step is often missed?
Plug the dock's USB-C cable into the laptop's USB-C port, then connect the included 135 W AC adapter to the dock's DC-in jack; the step often missed is powering the dock before the laptop.
What will need replacement on the 40AJ0135US after extended daily use?
The 135 W AC adapter and the USB-C cable are the parts most likely to need replacement after heavy daily use.
Which limit appears first when driving two external monitors from the 40AJ0135US continuously?
The combined video bandwidth of the two DisplayPort 1.4 outputs and the HDMI 2.0 port sets the practical resolution and refresh-rate ceiling during sustained multi-monitor use.
