Replacing The Battery - Fujitsu Lifebook P771 User Manual

Low Battery State
When the battery is running low, the Battery Level indicator will glow red. If you do not respond to the
low battery alarm, the batteries will continue to discharge until they are too low to operate. Your notebook
will then go into Sleep mode to try and protect your data for as long as possible. There is no guarantee that
your data will not be lost once the system reaches this point.

Once your notebook goes into Dead Battery Suspend mode you will be unable to resume operation until
you provide a source of power either from an adapter, or a charged battery. 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 maintained 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 system while an adapter is charging the battery.

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.

as an AC Adapter or charged modular battery), follow these easy steps: (Figure 24)
