Keyboard and mouse connected to the USB ports and connected. Nothing worked. Disconnected everything, removed computer, reconnected docking station, reconnected keyboard and mouse. Nothing yet. The adapter didn't fit either. It kept falling out. I repackaged it and sent it back. I was trying to save some money by purchasing this refurbished dock. I'll spend the extra money and buy a new one.
