Display Problems

If the OmniBook is on, but the screen is blank

∙Press the space bar or move the pointer to see if the computer is in Standby mode.

∙Press Fn+F1 or Fn+F2 to adjust the display brightness. If you are using an external keyboard, Fn=left CTRL + left ALT.

∙Press Fn+F5 in case the internal display was disabled. (Do this three times to return to the state you started from.)

∙If the OmniBook is cold, allow it to warm up.

If the screen is difficult to read

∙Check whether the display resolution is set to its default setting, such as 800 × 600 (SVGA) for a 12-inch display. Check this in Start, Settings, Control Panel, Display, Settings.

∙Check brightness (press Fn+F2 to increase brightness).

∙For Windows 98 or 2000, if the text looks blurred, check whether font smoothing is active. Check this in Start, Settings, Control Panel, Display, Effects.

If an external monitor doesn’t 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. See “To run the BIOS Setup utility” on page 86.

∙If the monitor is connected to a video adapter in a docking system, in BIOS Setup make sure the Primary Video Adapter is set to Auto in the Main menu.

If the image on an external monitor or projector is unstable

∙Press Fn+F5 to turn off the built-in display. (Do this three times to return to the state you started from.)

∙Change the display properties of the OmniBook display to match the resolution of the monitor or projector. In Control Panel, open Display, Settings and change the Desktop Area or Screen Area setting.
