Docking Your Laptop

The Microsoft programmers understood the need for mobile computing environments when they developed Windows XP. Mobile computing environments refer to those environments in which portable computers such as laptops are used. In the past few years, companies have begun developing docking stations for computer users who take a laptop with them on the road. Now they can come home and plug the laptop directly into a docking station. The docking station is a device that connects the laptop to a full-size color screen, printer, mouse, and keyboard. Therefore, the computer user uses the laptop on the road and then uses the laptop's system unit at home or in the office, with regular-size peripheral equipment.

Figure 17.1 shows a laptop connected to a docking station. Windows can detect whether a computer is docked and make appropriate adjustments instantly and accordingly. When undocked, Windows can use the laptop's screen, and when docked, Windows can immediately adjust the screen to a larger and higher-resolution monitor.

Windows XP can often recognize that a computer has been docked, but most hardware does not allow you to undock your PC without Windows knowing about the undocking. If Windows does not recognize the fact that you've undocked, you can select Eject PC from the Start menu, and Windows will know to reconfigure for the undocking and use the laptop's own configuration. For example, if your laptop contains an internal modem, the laptop, when undocked, will no longer be configured to use the docking station's modem.
