The OmniBook provides several safeguards so you won't be surprised by a
dead-battery condition, including the following:
♦
The battery status indicator shows the remaining battery charge.
♦
Built-in warnings are displayed for low-battery conditions.
♦
The OmniBook automatically turns off when the battery charge gets too
low—your session continues when you start recharging the battery or insert
a fresh battery.
Data on any of the drives is not affected by a low battery—unless the battery runs
down completely while writing data to the drive, or if the battery in a PC RAM card is
also low.
