Replacing The Battery - Fujitsu Lifebook E752 User Manual

Low Battery State
When the battery is running low, a low battery notification message will appear. If you do not respond to the low
battery message, the batteries will continue to discharge until they are too low to operate. When this happens, your
notebook will go into Sleep mode. There is no guarantee that your data will be saved once the notebook reaches this
point.

Dead Battery Suspend mode shows on the Status indicator just like the normal Sleep mode. 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
Power/Suspend/Resume button to resume operation.
In Dead Battery Suspend mode, data can be maintained for a while, but if a power is not provided promptly, the Power
indicator will stop flashing and go out, meaning you have lost the data that was not stored. Once power is provided,
you can use your notebook while an adapter charges the battery.
Shorted Batteries
The Status Indicator panel uses a symbol inside the battery outline of the Battery Level indicator to display the
operating level available in that battery. If this display shows a Shorted Battery, it means the battery is damaged and
must be replaced so it does not damage other parts of your LIFEBOOK notebook.
