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 HP Compaq laptop from the office to home or moving it from one room to another will no longer require disconnecting and reconnecting several devices.
