Lenovo ThinkPad Pro 135W Docking Station

The Lenovo 40AH0135US is a mechanical side-docking solution designed for compatible ThinkPad laptops. By seating the notebook onto the dock, you gain immediate access to power, displays, network, and peripherals through a single, secure connection. This approach keeps your desk clear of cable clutter and lets you move from mobile work to a fully equipped workstation in seconds.

The dock ships with a 135 W power adapter, so your ThinkPad receives full system power while charging its battery. Two DisplayPort outputs allow you to drive up to two external monitors, making multitasking on large spreadsheets, creative suites, or trading dashboards far more comfortable. Five USB ports give plenty of room for a full-size keyboard, mouse, external storage, and a phone or headset, with one USB-C port and a USB 3.1 Gen 1 port that provides always-on charging for devices even when the laptop is disconnected. Integrated Gigabit Ethernet delivers reliable wired connectivity, and enterprise-grade functions such as PXE boot, wake on LAN, and MAC address pass-through let IT teams manage systems remotely without extra adapters.

This dock fits naturally into offices where users routinely move between meeting rooms and a primary desk, hot-desking environments where multiple employees share workstations, or home offices that need a quick transition from laptop portability to a complete desktop setup. Anyone who depends on multiple monitors, fast peripheral access, and consistent power—ranging from engineers and analysts to creative professionals—will appreciate how much time the dock saves each day.

Because the dock attaches on the side using a mechanical latch, the notebook stays securely in place and can be locked with a Kensington cable for additional security. Once installed, the system instantly recognizes connected devices, so you can focus on your work instead of juggling cables.
