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.

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 switch, or remove all power
sources, battery, AC adapter or auto/air-
line adapter, while your notebook is in
Suspend mode any data which has not
been saved to the hard drive will be lost.
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
multiple 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 manage-
ment settings do not affect what happens at the
dead battery alarm level. Your notebook will go
to Suspend mode. 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 some time. 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 page 16 for shutdown procedures.)

There is no guarantee that data will not
be lost once your notebook enters the
Dead Battery Suspend mode.
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, or a charged bat-
tery. Dead Battery Suspend mode shows on the
