There is no memory effect on the Lithium-Polymer battery, therefore you do not need to discharge the battery
completely before recharging. The charge times will be significantly longer if your LIFEBOOK is in use while the
battery is charging. If you want to charge the battery more quickly, put your LIFEBOOK into Standby mode, or turn it
off while the adapter is charging the 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 battery will continue to discharge until too low to operate. When this happens, your LIFEBOOK
will go into Sleep mode. There is no guarantee that your data will not be lost once the LIFEBOOK reaches this point
Note that you can change the state in which the battery goes into Sleep mode in the Control Panel "Power" properties.

Dead Battery Suspend mode shows on the Status indicator just like the normal Sleep mode. Once your LIFEBOOK 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 Ultrabook 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 by
Fujitsu technicians.
