Mechanical Side-Docking Station

The Lenovo ThinkPad Pro Docking Station 40AH0135US is a mechanical side-docking station designed for select 2018 ThinkPad L Series, T Series, X Series and X1 Series laptops. It connects through the proprietary side connector and includes a 135 W Slim Tip power adapter to run the laptop and peripherals from a single cable.

Compatibility

This station suits owners of a P52s, L580, L480, T580, P580p, T480s, T480, X1 Carbon Gen 6 or X280 who want a permanent desk setup with dual DisplayPort 1.4 video outputs, Gigabit Ethernet and multiple USB ports. Buyers whose laptops lack the mechanical side-docking connector cannot use this station.

135 W Slim Tip Power Adapter

The included 135 W Slim Tip power adapter delivers enough power for the docked laptop and supports ThinkPad RapidCharge. If your laptop requires a different wattage or connector type, this docking station will not provide the correct charging profile.
