Hints

To respond to a low-battery warning or shutdown

When battery power is critically low, the OmniBook automatically shuts off, preserving
your current status and all information. Before this occurs, however, you receive a low
battery warning—the Battery Status indicator in the LCD Status Panel appears empty
and starts to flash. By connecting the ac adapter or installing a fresh battery, you can
continue your work uninterrupted.
C A U T I O N
If you don't restore power and you don't save your work before the OmniBook
turns itself off, your current session will be lost if the battery runs down
completely—within as little as several hours after the warning. If you have a
PCMCIA I/O card installed, unplug it to conserve the remaining power.
Data you've saved on any of the disks isn't affected by a power loss. However, if you
continue writing to a disk when the warning period expires, you could corrupt the
disk if the battery runs down completely.
After the warning period, the OmniBook automatically turns off to preserve your current
session as long as possible—you won't be able to turn it on again until you restore
power. The battery is able to provide the small amount of power required to preserve
memory for several hours or more. If you try to turn on the OmniBook again without
restoring power, it beeps and refuses to turn on (to preserve memory). However, if you
do this repeatedly, you may exhaust the remaining power and lose your current session.

To replace the battery

You may never need to remove the rechargeable battery pack in ordinary use—you just
connect the ac adapter to the OmniBook and recharge the pack when it's depleted.
However, you can replace the pack if it's low with another battery pack that's more fully
charged.
C A U T I O N
If you have the ac adapter plugged in when you remove the battery, do not
disconnect it while the battery is out. If you do, your current session in memory will
be lost.
To get the longest battery operating time, allow the battery to charge fully—until
the battery symbol in the Status Panel fills completely. Continued charging
maintains the full charge.
You can recharge the battery pack whenever it's convenient—it doesn't suffer from
the "memory" effects that may affect other types of rechargeable batteries.
Plug in the ac adapter—see the previous topic.
