"This Port Replicator / Docking station allows for permanent connection of peripheral devices at your desk with no need to keep plugging / unplugging cables each time you want to work.
Taking your Dell from the office to home or moving it from one room to another will no longer require disconnecting and reconnecting several devices.
The docking station replicates all of the connectors and ports from your laptop and routes the connectors to the back of the dock.Worked fine last time I used it."
No longer have the laptop so I can't test it, but had very little use and is in good nick.
