If battery indicator is inaccurate
• After extended use with ac power, the battery indicator may no longer reliably
report the actual charge on the battery. To improve the accuracy of this
indicator, use the following procedure to run 2 to 4 cycles of battery
charging/discharging.
1. Connect the ac adapter and charge the battery to full capacity.
2. Unplug the ac adapter and leave the OmniBook on until the battery is fully
discharged and the system turns off. If you are not using the OmniBook
during this step, you can temporarily customize the
time-out settings in the
BIOS Setup utility to speed up the discharging.
If the battery doesn’t charge
• Make sure the ac adapter is plugged into the power source.
•
Check that the battery module is fully installed and locked in place.
• 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 a secondary battery doesn’t charge
• A 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 a seconary battery module is fully installed and locked in place.
If the OmniBook stops responding
•
Press the blue power button and wait a few moments until the icons on the
status panel stabilize. Then press the power button again to turn the OmniBook
back on.
• If nothing happens, insert a paper clip into the system-off button; see "To reset
the OmniBook."
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.
