Lenovo 40A40090EU laptop dock/port replicator Wired USB 3.2 Gen 1 (3.1 Gen 1) Type-A Black

The Lenovo ThinkPad OneLink+ Dock (model 40A40090EU) expands a compatible ThinkPad into a full workstation by providing power, wired network access and multiple peripheral connections through a single OneLink+ connector. The dock supports up to Ultra High Definition video output, multiple USB ports for data and device charging, Gigabit Ethernet and legacy video via VGA, and includes a 90 W slim-tip AC adapter for reliable power delivery.

Advantages

The OneLink+ Dock delivers uncompressed video with no additional drivers and minimal impact on laptop performance, while a single OneLink+ cable provides continuous power and data connectivity. Front and rear USB ports include USB 3.0 (USB 3.2 Gen 1) for faster transfers and an "always-on" front port for charging mobile devices. Dual DisplayPort 1.2 outputs plus a VGA port and Gigabit Ethernet allow flexible multi-monitor and wired networking configurations. The dock also supports cable-lock security and occupies less desk space than many traditional docking stations.

Attach monitors to the DisplayPort and VGA outputs as required, and connect peripherals such as keyboard, mouse and printer to the available USB ports. Plug an Ethernet cable into the RJ-45 port for wired network access. Use the dock power button to control system power if available on your laptop model.

Recommendations

For the best multi-monitor performance, use DisplayPort 1.2 connections and ensure your ThinkPad model supports OneLink+ video output. Use the front "always-on" USB port to charge mobile devices even when the laptop is in sleep mode. Secure the dock with a cable lock when used in shared or public environments.
