- Lithium ion Battery
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
LIFEBOOK notebook will go into Sleep mode. There is no guarantee that your data will not be lost once the notebook
reaches this point
.
Note that you can change the state in which the battery goes into Sleep mode in the Power properties of the Control
Panel.
Dead Battery Suspend mode shows on the Status indicator just like the normal Sleep 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 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 LIFEBOOK notebook while the adapter
is charging the battery.
