The Lenovo ThinkPad Thunderbolt 4 Workstation Dock (40B00300UK) is Lenovo’s top-tier docking solution, engineered for ThinkPad mobile workstations and power users who need maximum display ouTPUt and up to 230W of charging from a single dock. A 0.7m Thunderbolt 4 split cable carries data, video and a dedicated Slim Tip power line, so your workstation stays fully powered even under heavy CPU/GPU load.

Unlike a standard 100W USB-C dock, the Workstation Dock uses a 300W power adapter and a Slim Tip charging path to deliver up to 230W to compatible ThinkPad workstations — the difference between throttling and running at full performance while docked.

This is the dock to choose when the laptop is a ThinkPad mobile workstation (P-series or high-wattage T/X models) and 100W simply is not enough. The 230W Slim Tip path is the defining feature: it keeps a power-hungry workstation at full clocks while a four-monitor setup, Gigabit network and USB peripherals all run off one cable. For a standard ultrabook, a 100W ThinkPad Universal Thunderbolt 4 dock is more cost-effective — the Workstation model earns its place specifically on charging headroom and display count.

It fits naturally into our docking stations range for anyone standardising a ThinkPad workstation desk, and the Gigabit port pairs well with a wired-network upgrade using faster network cards where higher throughput is needed elsewhere on the LAN.
