Troubleshooting
Power Failures
You turn on your LifeBook
notebook and nothing
seems to happen.
The installed battery is
completely discharged or there
is no power adapter (AC or
Auto/Airline) installed.
Check the Status Indicator Panel to determine the
presence and condition of the battery. 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 battery. 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 is low. Check the Status Indicator Panel to determine the
presence and condition of the battery. See “Status
Indicator Panel” on page 13. Use a power adapter
until a battery is charged or install a charged battery.
The AC or auto/airline adapter
is not plugged in properly.
Verify that your adapter is connected correctly. See
“Power Sources” on page 27.
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.
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
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.
You are operating on battery
power and have ignored a low
battery alarm until the battery
is at the dead battery state and
your machine has gone into
Dead Battery Suspend mode.
Install a power adapter and then push the Suspend/
Resume button. See “Power Sources” on page 27.
You have a battery failure. Verify the condition of the battery using the Status
Indicator panel, and replace or remove any shorted
battery. See “Status Indicator Panel” on page 13.
Your power adapter has failed
or lost its power source.
Make sure the adapter is plugged in and the outlet
has power.
Your notebook will not
work on battery alone.
The installed battery is dead. Replace the battery with a charged one or install
a power adapter.
No battery is installed. Install a charged battery.
The battery is improperly
installed.
Verify that the battery is properly connected
by re-installing them.
