Lenovo ThinkPad Ultra Docking Station

The Lenovo 40AJ0135US is the official ThinkPad Ultra Docking Station, a mechanical dock that expands the capabilities of compatible ThinkPad laptops through a secure side-connector interface. Once latched, your notebook gains immediate access to desktop-class connectivity without the clutter of multiple cables.

The dock can drive up to three external monitors thanks to two DisplayPort 1.4 outputs, one HDMI 2.0 port, and a legacy VGA connector. Designers, data analysts, and multitaskers can spread applications across multiple screens for a more spacious and efficient workspace.

Four USB 3.1 Gen 2 Type-A ports handle high-speed peripherals such as external drives and webcams, while two USB-C ports support newer accessories. One of the USB-A ports stays powered even when the laptop is sleeping, letting you charge a phone or headset at any time. A gigabit Ethernet jack delivers wired network performance that remote workers and office users rely on for stable video calls and fast file transfers.

IT departments will appreciate built-in management features that include PXE boot, Wake-on-LAN, and MAC address pass-through. A mirrored power button lets users start or shut down the laptop without opening the lid, and an integrated key lock slot adds a layer of physical security in shared environments such as hot-desk stations or classroom labs.

Lenovo supplies a 135-watt slim-tip power adapter with the dock, so the notebook charges while connected. Whether you are setting up a permanent workstation at home or equipping an entire office floor, this dock delivers a clean, single-click connection to power, displays, and peripherals.
