Troubleshooting
Solving Problems
• Turn off the OmniBook, then check that the battery contacts are clean and that
the ac adapter cables are fully plugged in.
• Move the OmniBook away from any nearby heat source. Unplug the ac adapter
and allow the battery to cool down. An elevated battery temperature prevents
charging.
• If available, try another battery and ac adapter.
If the secondary battery doesn't charge
• The OmniBook's secondary battery doesn't charge until the main battery is fully
charged.
• Make sure the ac adapter is plugged into the power source.
• Check that the light on the ac adapter is on.
• Check that the secondary battery module is fully installed and locked in place.
If the OmniBook stops responding
• Press CTRL+ALT+DEL to end the application that is not responding.
• Press the blue power button to suspend the OmniBook. Then press the blue
button again to turn the OmniBook back on.
• If nothing happens, insert a paper clip into the system-off button. Press the blue
power button to turn the OmniBook on.
If the OmniBook doesn't suspend as expected
• If you have a connection to another computer, the OmniBook doesn't suspend if
the connection is actively in use.
• If the OmniBook is performing an operation, it normally waits for the operation
to finish.
• Check the Power Button Mode in the BIOS Setup utility (Power menu). You can
configure the power button to either suspend or shut down the OmniBook.
• If a CD-ROM drive is present, make sure auto insert notification is disabled. This
is the default factory setting. In Windows 95 or Windows 98, view the CD-ROM
drive properties in Device Manager.
