With the Mobility Center panel, you can adjust your display brightness and volume, check your battery status, change your power settings, and turn your wireless on and off, among other tasks. It's all in one place, so you don't need to go hunting around for settings when you move from your desk to a meeting or your home to the airport. (You might see different options depending on your hardware and PC manufacturer.)
Designed for laptops, Windows Mobility Center makes it easier to work from anywhere.
