What it is

• It’s a single‑cable dock that connects to your laptop via USB‑C/Thunderbolt and then provides multiple ports for monitors, peripherals, and power.

• Officially branded as ThinkPad Universal USB‑C Dock, with product code 40AY0090 (LDA‑KP is the SKU / ordering code).

Key features

• Up to 90–100 W laptop charging over USB‑C, so it can power many ThinkPads and other USB‑PD laptops from one cable.

• Multiple ports typically include HDMI, DisplayPort, Ethernet, USB‑A, audio, and sometimes additional USB‑C, allowing you to run dual external displays plus keyboard, mouse, and network.

Typical use cases

• Office workstation: plug in one USB‑C cable to your ThinkPad and instantly get dual monitors, LAN, and USB peripherals.

• Hot‑desking / flexible workspaces: easy plug‑and‑unplug between laptops (Windows and some Macs, though macOS multi‑monitor support can be limited on some models).
