Exit and restart the application-and plug in the ac adapter, if possible. If you have problems with infrared communications • Check that only one application is using the infrared port. • Check that both devices are using the same protocol, such as IrDA. Sound Problems If sounds aren't audible • Check the playback or recording sound levels, channels, and muting-in OmniBook Tools, click Sound, then Volume and Mixer. • Press FN+F9 several times to make sure the upper sound limit isn't too low. Display Problems • Check whether the display resolution is set to its default setting-see "To change the display type" • Try changing the display setting to the VGA option. See "To change the display type." If the display scrolls when the pointer reaches the edge • A high-resolution display setting is active-you can use an external display and turn off the OmniBook display, or you can choose the default OmniBook display setting.

an update to avoid power-management problems.
Remember to enable Power

If an I/O card stops communicating properly
•
It may have been reset if the OmniBook turned off. Exit and restart the
application—and plug in the ac adapter, if possible.
If you have problems with infrared communications
•
Check that only one application is using the infrared port.
•
Check that both devices are using the same protocol, such as IrDA.
Sound Problems
If sounds aren’t audible
•
Check the playback or recording sound levels, channels, and muting—in
OmniBook Tools, click Sound, then Volume and Mixer.
