LifeBook N Series User’s Guide

Dead Battery Suspend mode shows on the Status indi-

cator just like the normal Suspend mode. Once your

LifeBook notebook goes into Dead Battery Suspend

mode you will be unable to resume operation until you

provide a source of power from an AC adapter. Once you

have provided power, you will need to press the

Suspend/Resume button to resume operation. In the

Dead Battery Suspend mode, your data can be main-

tained for some time, but if a power source is not

provided promptly, the Power indicator will stop

flashing and go out, meaning that you have lost the data

that was not stored. Once you provide power, you can

continue to use your LifeBook notebook while the

adapter is charging the battery.

Shorted Batteries

The Status Indicator panel displays the battery status via

the Battery Status indicator to show the charge level

available in that battery. If the display is flashing red, it

means that the battery is damaged and must be replaced

so it does not damage any other parts of your LifeBook

notebook.

REPLACING THE BATTERY

With the purchase of an additional battery, you can have

a fully charged spare to swap with one that is not

charged.

Follow the steps below to replace a battery (Figure 4-3):

1. Have a charged battery ready to install.

2. Shut down your notebook and disconnect the AC

adapter.

3. Turn the system over.

4. Press the two battery latches towards the battery

pack.

5. Lift the battery and remove it from the bay.

6. Place a charged battery into the bay and press it

down until the latches click into place. (Figure 4-4)

7. Plug in the AC adapter and turn the power on.
