A docking station or port replicator provides a way to connect your laptop to several devices like mouse, keyboard, speakers, monitor, Ethernet. Using a docking station that is connected to several devices helps gain the benefits of a desktop computer without sacrificing the portability of a laptop.
Dell rugged or E-port docking stations use a proprietary docking connector to dock a compatible Dell laptop.
Before you initially connect your laptop to the docking station, the operating system must complete its setup process.
CAUTION: Always use the Dell AC adapter that came with the docking station. If you use any other commercially available AC adapter, you may damage the docking station or the laptop.
