Problem
You turn on your LIFEBOOK
notebook and nothing
seems to happen.
(continued)
Your LIFEBOOK notebook
turns off all by itself.
Your notebook will not work
on battery alone.
Possible Cause
The primary battery is
installed but is faulty.
The battery or batteries are
low.
The power adapter is not
plugged in properly.
The power adapter (AC or
auto/airline) is faulty.
AC adapter has no power
from AC outlet, airplane seat
jack, or car cigarette lighter.
Power management parame-
ters are set for auto timeouts
which are too short for your
needs.
You have a battery failure.
You are operating on battery
power and ignored a low bat-
tery alarm until battery is
dead and system is in Dead
Battery Suspend mode.
Your power adapter has
failed or lost its power.
No battery is installed.
Installed battery is dead.
Possible Solutions
Use the Status Indicator panel to verify the presence and condition of the batter-
ies. See "Status Indicator Panel" on page 22. If a battery short is indicated,
remove the battery and operate from an AC Adapter or replace the battery.
Check the Status Indicator Panel to determine the battery(s) condition. See
"Status Indicator Panel" on page 22. Use power adapter to operate until a bat-
tery is charged or install a charged battery.
Verify that your adapter is connected correctly. See "Power Sources" on
page 44.
Try a different Power adapter or install a charged optional second battery.
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.
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 man-
agement settings, or close your applications and go to the Power Options Prop-
erties in the Control Panel to adjust the timeout values to better suit your needs.
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.
Install a power adapter and then push the Power/Suspend/Resume button. See
"Power Sources" on page 44.
Make sure the adapter is plugged in and the outlet has power.
Install a charged battery.
Replace the battery with a charged one or install a power adapter.
