Low Battery State
When the battery is running low, your note-
book beeps about every 15 seconds and the
Battery Level indicator flashes. If you do not
respond to the low battery alarm, the battery
will continue to discharge until it is too low to
operate. When this happens there will be a mul-
tiple beep alarm, the Battery Level indicator will
show dead battery, and your notebook will go
into Suspend mode to try and protect your data
as long as possible. Your power management
settings do not effect what happens at the dead
battery alarm level. Your notebook will go to
Suspend mode. (Figure 3-4 on page 23.)

You may not be able to hear the audio
alarms if the volume control is set too
low or is turned off by either hardware or
software but you will still be able to see
the Battery Level indicator flash.

When the low battery alarm occurs, you need to
save all your active data and put your notebook
into Suspend mode until you can provide a new
power source. You should provide this power as
soon as possible. The new power source can be
a charged battery or a power adapter, either AC
or auto/airline.
C A U T I O N
When you are in Suspend mode there
must always be at least one power source
active. If you turn off the power with
the power button, or remove all power
sources, battery, AC adapter or auto/
airline adapter, while your notebook is in
Suspend mode any data which has not
been saved to the hard drive will be lost.
Once your notebook goes into Critical Low
Battery Suspend mode, you will be unable to
resume operation until you provide a source of
power either from an AC adapter, an optional
auto/airline adapter, or a charged battery.
Critical Low Battery Suspend mode shows on
the Status indicator just like the normal
Suspend mode. Once you have provided
power, you will need to press the Suspend/-
0Resume button to resume operation. In the
Suspend mode, your data can be maintained
for sometime. If a power source is not provided
promptly, the Power indicator will stop flashing
and go out, and you will have lost the data that
was not stored.
Once you provide power, you can continue to
use your notebook while an adapter is charging
the battery. However, this charges the battery
more slowly. If you want to charge the battery
quickly, put your notebook into Suspend Mode,
or turn it off while the adapter is charging the
battery. (See Power Off on pages 20-21 for
shutdown procedures.)

There is no guarantee that data will not
be lost once your notebook enters the
Dead Battery Suspend mode.
