Problem
You turn on your LIFEBOOK note-
book and nothing seems to hap-
pen.
(continued)
Your LIFEBOOK notebook turns off
all by itself.
Your LIFEBOOK notebook will not
work on battery alone.
Possible Cause
The installed primary battery
is completely discharged,
there is no optional second
battery installed or there is
no power adapter installed.
The power adapter has no
power from the AC outlet, air-
plane seat jack, or cigarette
lighter.
The power adapter (AC or
auto/airline) is faulty.
The power management
parameters are set for auto
timeouts which are too short
for your operating needs.
You are operating on battery
power and ignored a low bat-
tery alarm until the system
has gone into Dead Battery
Suspend mode.
You have a battery failure.
Power adapter lost its power
source or failed.
The batteries are dead.
No batteries installed.
Possible Solutions
Check the Status Indicator Panel to determine the presence and condition of the
batteries. See "Status Indicator Panel" on page 22. Install a charged battery
or a Power adapter.
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.
Press any button on the keyboard, or move the mouse to restore operation. If
that fails, push the Power/Suspend/Resume button. Check your power manage-
ment settings, or close your applications and go to the Power Options Properties
located in the Control Panel to adjust the timeout values to better suit your
needs.
Install a power adapter and then push the Power/Suspend/Resume button. See
"Power Sources" on page 43.
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 22.
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.
