Windows implements a mobility centre to quickly adjust your computer's settings before giving a presentation. Included in Windows Vista and Windows 7, Microsoft Windows Mobility Center was created to centralise the most common computer settings. While using the Windows Mobility Center, you can check your network connectivity and battery status, adjust the volume and screen brightness, turn off the screensaver, and prevent notifications from appearing on your computer during a presentation.
Press the "Windows Key" and "X" simultaneously. The Windows Key is located in the lower-left corner of your keyboard, usually between the CTRL and ALT keys. If you cannot locate the Windows Key, you can click "Start" and select "Control Panel." Click "Mobile PC" and then "Windows Mobility Center." The Windows Mobility Center dialogue box appears on your screen.
Press the button labelled "Turn On" in the Presentation Settings box. Close the dialogue box.
Connect your computer to a network projector or an additional monitor to set up your presentation. The New Display Detected dialogue box will appear on your screen. Click the "OK" checkbox next to "Turn on Presentation Settings."
Give your presentation. When you are finished, you can turn off the Presentation Settings by clicking "Windows Key" and "X" again and selecting "Turn Off" on the Presentation Settings box.
Alternately, you can turn off the screen saver by right clicking on your desktop and selecting "Personalize." Select "Screen Saver" and then turn it off. This technique is often disabled in corporate or educational settings to protect the computer.
