80 - Troubleshooting

Your LifeBook notebook 
turns off all by itself.
(continued)

You are operating on 
battery power and 
ignored a low battery 
alarm until the battery is 
at the dead battery 
state 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.

Your LifeBook 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 batteries are 
improperly installed.

Verify that the batteries are properly connected by re-installing 
them.

Your installed batteries



are faulty.

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 21.

The batteries seem to 



discharge too quickly.

You are running an 
application that uses a 
lot of power due to fre-
quent hard drive or opti-
cal drive access, or use 
of a modem, LAN PC 
card, Wireless LAN, or 
Bluetooth device.

Use both the primary battery and an optional second battery 
and/or use a power adapter for this application when at all 



possible.

The power savings fea-
tures may be disabled.

Check the Power Options menu settings and adjust according to 
your operating needs.
