Troubleshooting and Maintenance Troubleshooting Your Computer Display Problems If the computer is on, but the screen is blank • Move the mouse or pointing stick, or tap the touch pad. This will wake the display if it is in Display-off mode. • Press Fn+F5 in case the internal display was disabled. (Do this three times to return to the state you started from.) • If the computer is cold, allow it to warm up. If the screen is difficult to read • Try setting the display resolution to its default setting of 1024×768 or higher, depending on your model: click Start, Settings, Control Panel, Display, Settings (Windows 98 or 2000) or Start, Control Panel, Appearance and Themes, Display (Windows XP). • Try adjusting the size of the desktop icons and labels-see "To adjust the display" on page 37. If an external display does not work • Check the connections. • Press Fn+F5 in case the external monitor was disabled. (Do this three times to return to the state you started from.) • The external monitor may not be detected. In the BIOS Setup utility, try setting Video Display Device to Both in the Main menu. • If you're using a TV connected to the S-video port, you must activate the TV-see "To use a TV set as a monitor" on page 85. • Test the display with the e-Diagtools diagnostics. See "Testing the Hardware" on page 175. If an external display cannot use high resolutions • For Windows 98, use the default display type for the internal display: Default Monitor. If you change the display type, non-Plug-and-Play (non-DDC) external monitors will not be able to use resolutions higher than the resolution of the internal display. You can check display settings using Display in Control Panel, or by rightclicking the desktop and then clicking Properties. Corporate Evaluator's Guide 155
