Laptop dock/port replicator Lenovo 40A70045IT — Wired USB 3.2 Gen 1 Type-B, Gigabit Ethernet, DC power, black
Lenovo 40A70045IT is a wired laptop dock and port replicator designed to expand connectivity for compatible notebooks. The compact black unit provides a USB 3.2 Gen 1 (3.1 Gen 1) Type‑B host interface for a single-cable connection to a laptop, integrated Gigabit Ethernet for stable wired network access, and DC power input for operation. With a small footprint (150 × 80 × 32 mm) and multiple safety and compliance certificates, this dock enables connection of peripherals and network resources in a desktop-style setup.
The dock offers a simple single-cable method to add wired network access and multiple peripheral connections to a laptop. Its USB 3.2 Gen 1 host interface supports high-speed data transfer for connected devices, while the built-in Gigabit Ethernet port provides reliable LAN performance for tasks that require stable throughput. The compact black housing and standardized power input make it suitable for dense workspaces and mobile professionals who need a consistent docking solution.
Connect the dock to a compatible laptop using the USB 3.2 Gen 1 Type‑B to Type‑A/Type‑C cable supplied or specified for your setup, then plug in the external AC power adapter to the dock's DC input to power the unit. Attach your Ethernet cable to the Gigabit LAN port for network access and connect USB peripherals such as external drives, printers, keyboard and mouse to the available USB ports. After connection, allow the operating system to detect and configure standard drivers; some systems may require manual driver installation or updates for full functionality. Use the single host cable to dock and undock quickly while maintaining connections to peripherals and network resources.
Use a high-quality USB 3.0/3.2 cable and the appropriate AC adapter rated for the dock to ensure stable performance. Place the dock on a flat, ventilated surface and connect it to a Gigabit-capable network for optimal wired throughput. If multiple displays are needed, verify host laptop display output capabilities and available video adapters or converters before purchase.
