Power Failures
You turn on your
LifeBook 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 13. 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 13. 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 13. 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.
You turn on your LifeBook
and nothing seems to
happen. (continued)
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.

On position.
Slide your power switch firmly to the Off position,
pause 10 seconds or more and then firmly to the
On position.
