The power management parame-
ters are set for auto timeouts

low battery alarm until the
batteries are all at the dead battery
state and your machine has gone
into Dead Battery Suspend mode.
You have a battery failure.

Possible Solutions
Use the Status Indicator panel to verify the presence
and condition of the batteries. (See Status Indicator
Panel on page 13 for more information) If a battery is
indicating a short, remove that battery and operate
from another power source or replace that battery.
Check the Status Indicator Panel to determine the
presence and condition of the batteries. (See Status
Indicator Panel on page 13 for more information) Use
a Power adapter to operate until a battery is charged
or install a charged battery.
Verify that your adapter is connected correctly. (See
Power Sources on page 25 for more information)
Move the AC cord to a different outlet, check for
a line switch or tripped circuit breaker for the AC
outlet. If you are using an auto/airline adapter in
a car make sure the ignition switch is in the On or
Accessories position.
Try a different Power adapter or install a charged
optional second battery.
Slide your power switch firmly to the Off position,
pause 10 seconds or more and then slide it firmly to
the On position.
Press any button on the keyboard, or move the
mouse to restore operation. If that fails, push the
Suspend/Resume button. Check your power
management settings, or close your applications and
go to the Power Savings menu of the setup utility to
adjust the timeout values to better suit
your operation needs.
Install a power adapter and then push the Suspend/
Resume button. (See Power Sources on page 25 for
more information)
Verify the condition of the batteries using the
Status Indicator panel, and replace or remove
any batteries that are shorted. (See Status Indicator
Panel on page 13 for more information)
Make sure the adapter is plugged in and the outlet
has power.
Replace the battery with a charged one or install a
Power adapter.
Install a charged battery.
Verify that the batteries are properly connected by
re-installing them.
