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.
