Low Battery State
When the battery is running low, your note-
book beeps about every 15 seconds and the
Battery Level indicator(s) flash. If you do not
respond to the low battery alarm,the battery
will continue to discharge until it is t oo 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 affect what happens at the dead
battery alarm level. Your notebook will go to
Suspend mode. (Figure 3-1 on page 26.)
C A U T I O N
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(s) 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 sourc e
active. If you turn off the power with
the power switch, or remove all power
s o u rces, 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 Dead 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. Dead
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/Resume 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, but the battery trickle charges under
these conditions. If you want to charge the
battery more quickly, put your notebook into
Suspend mode, or turn off your notebook while
the adapter is charging the battery. (See Power
Off on pages 21-22 for shutdown procedures.)
