CHAPTER 6: Troubleshooting Liquid spilled in the keyboard • If you spilled liquid in the keyboard, turn off your computer and unplug the keyboard. Clean the keyboard and turn it upside down to drain it. Let the keyboard dry before using it again. If the keyboard does not work after it dries, you may need to replace it. Media Center This section only covers problems relating to Media Center mode. Media Center mode is available only on Windows Vista Home Premium and Ultimate versions. To view Media Center troubleshooting information that is not covered in this section, go to the Gateway support Web Site at www.gateway.com. Help For more information about Windows Media Center, click Start, then click Help and Support. Type the phrase Media Center in the Search Help box, then press ENTER. The Media Center video display looks bad on your TV Many factors, such as the display type, quality of the video source, type of connection used, quality of video cables, display device screen resolution, size of TV, age of the TV, or the type of TV (interlaced or progressive scan), can affect the video quality significantly: • Display type-The Media Center is best viewed on computer displays. Other types of display devices, including retail TVs, may provide lower quality video. If you did not order a display device when you purchased your computer, a progressive scan display device with a VGA input is the best choice. • Quality of video source-The quality of the video signal coming into the computer has an affect on the video quality. The video displayed from Media Center is only as good as the source video signal. Cable, digital cable, and satellite usually provide better quality than an antenna. 82
