- Troubleshooting
You turn on your LIFE-
BOOK notebook and noth-
ing seems to happen.
(continued)
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 20.
If a bat-
tery 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 (see page 20) to determine the
presence and condition of the batteries.Use a Power adapter to
operate until a battery is charged or install a charged battery.
The power adapter is
not plugged in properly.
Verify that your adapter (AC or auto/airline) is connected correctly.
See “Power Sources” on page 33.
The power adapter has
no power from the AC
outlet, airplane seat
jack, or 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.
Your LIFEBOOK notebook
turns off all by itself.
The power manage-
ment 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 applica-
tions and go to the Power Options Properties located in the Con-
trol Panel to adjust the timeout values to better suit your needs.
You have a battery
failure.
Verify the battery condition using the Status Indicator panel (see
page 20), and replace or remove any batteries that are shorted.
You are operating on
battery power and
ignored a low battery
alarm until the battery is
dead and the system
has gone into Dead Bat-
tery Suspend mode.
Install a power adapter and then push the Power/Sus-
pend/Resume button.
See “Power Sources” on page 33.
Your power adapter has
failed or lost power.
Make sure the adapter is plugged in and the outlet has power.
