Overview
Designed exclusively for ultraslim HP EliteBook Notebook PCs, the HP UltraSlim Docking Station expands display, network, and device connectivity so you can be more productive throughout the day—all through a simple one-click slide-in side dock. 
Features
Four USB 3.0 ports offer high-speed connectivity to the USB devices you use most. USB 3.0 reduces the time required for data transmission (vs. USB 2.0), is backward compatible with USB 2.0, and is bi-directional. 
DisplayPort and VGA ports deliver legacy and future compatibility with your choice of video devices and an Ethernet/LAN port keeps you online. 
Headphone and microphone jacks support your multimedia and videoconferencing requirements. 
The optional HP Docking Station Cable Lock secures the connected notebook to the dock. 
Get the peace of mind of a one-year limited warranty. Additional support is available (North America only) seven days a week, 24 hours a day by phone as well as through online support forums.
