- 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.
