- Lithium ion Battery
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 Standby 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
Your notebook comes with one battery pack; you might want to consider purchasing a spare. By keeping
a spare battery fully charged, you can immediately swap with one that is not charged.
There are two ways to swap batteries: cold- and hot-swapping. Cold-swapping means swapping batteries
when the system is powered down; hot-swapping is performed when the system is powered by AC power:
USING HEAVY CURRENT DEVICES OR FREQUENT EXTERNAL OPTICAL DRIVE ACCESSES MAY PREVENT
CHARGING COMPLETELY.
■
ONCE THE LOW BATTERY NOTIFICATION MESSAGE APPEARS, YOU NEED TO SAVE ALL YOUR ACTIVE DATA AND PUT
YOUR LIFEBOOK NOTEBOOK INTO STANDBY MODE UNTIL YOU CAN PROVIDE A NEW POWER SOURCE. YOU SHOULD
PROVIDE A CHARGED BATTERY, AN AC POWER ADAPTER, OR AUTO/AIRLINE ADAPTER AS SOON AS POSSIBLE.
■
WHEN YOU ARE IN STANDBY MODE THERE MUST ALWAYS BE AT LEAST ONE POWER SOURCE ACTIVE. IF YOU
REMOVE ALL POWER SOURCES WHILE YOUR LIFEBOOK NOTEBOOK IS IN STANDBY MODE, ANY DATA THAT HAS NOT
BEEN SAVED TO THE HARD DRIVE WILL BE LOST.
