Docking station for select ThinkPad models

The Lenovo 40A10090US ThinkPad Pro Dock is a 90W docking station designed for compatible 65W and 90W ThinkPad laptops with integrated graphics. It connects a single cable to provide power, wired network access and multiple peripheral ports for office workstations. The dock includes a matching 90W AC adapter and supports always-on charging on one USB 2.0 port.

Upgrade from basic port replicators

This dock replaces simpler port replicators by adding Gigabit Ethernet, three USB 3.0 ports and three video outputs: DisplayPort 1.2, DVI-D and VGA. The jump is worth it when you need two external displays, as DisplayPort and DVI-D share an exclusive signal path. It is not recommended for laptops that ship with a 170W adapter.

Check laptop power and video needs

Verify that your ThinkPad model appears in the supported list and uses a 65W or 90W adapter. Confirm your monitors accept DisplayPort 1.2, DVI-D or VGA input and that you do not require simultaneous DisplayPort and DVI-D output. The dock measures 13.6 by 6.4 by 2.2 inches and weighs 2.01 lbs.

Questions about this item

How much desk space does the 13.6" x 6.4" x 2.2" dock require?

The unit measures 13.6 inches wide by 6.4 inches deep by 2.2 inches high and weighs 2.01 lbs, so allow that footprint plus cable clearance on a flat surface.

What is the correct way to connect the included 90W AC adapter before docking the notebook?

Plug the supplied 90W ThinkPad AC adapter into the dock’s power input and a wall outlet first, then slide the compatible ThinkPad down onto the connector until it clicks securely.

Which laptops will stop being supported if they require a 170W power supply?

The dock is not recommended for models that ship with a 170W adapter; it only supports listed 65W and 90W ThinkPads such as the T440, T450, T460, L440, L450, L460 and P50s series.
