Troubleshooting
Power Failures
You turn on your
LifeBook notebook and
nothing seems to happen.
The installed primary battery
is completely discharged, there
is no optional second battery
installed or there is no Power
adapter (AC or Auto/Airline)
installed.
Check the Status Indicator Panel to determine the
presence and condition of the batteries. (See Status
Indicator Panel on page 12 for more information)
Install a charged battery or a Power adapter.
The primary battery is
installed but is faulty.
Use the Status Indicator panel to verify the presence
and condition of the batteries. (See Status Indicator
Panel on page 12 for more information) If a battery is
indicating a short, remove that battery and operate
from another power source or replace that battery.
The battery or batteries are low. Check the Status Indicator Panel to determine the
presence and condition of the batteries. (See Status
Indicator Panel on page 12 for more information) Use
a Power adapter to operate until a battery is charged
or install a charged battery.
The power adapter (AC or
auto/airline) is not plugged
in properly.
Verify that your adapter is connected correctly. (See
Power Sources on page 27 for more information)
The Power adapter (AC or
auto/airline) has no power
from the AC outlet, airplane
seat jack, or the car’s cigarette
lighter.
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.
The Power adapter (AC or
auto/airline) is faulty.
Try a different Power adapter or install a charged
optional second battery.
Your LifeBook notebook
turns off all by itself.
The power management
parameters are set for auto
timeouts which are too short
for your operating needs.
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
management 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.
You have a battery failure. 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 12 for more information)
You are operating on battery
power and ignored a low batt-
ery alarm until the batteries are
at the dead battery state and
the system has gone into Dead
Battery Suspend mode.
Install a power adapter and then push the Power/
Suspend/Resume button. (See Power Sources on
page 27 for more information)
Your power adapter has failed
or lost its power source.
Make sure the adapter is plugged in and the outlet
has power.
