- 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
With the purchase of an additional battery, you can have a fully charged spare to swap with one that is not
charged.
Swapping Batteries when Additional Power Source is not Available
To swap batteries in your battery bay when you don’t have another power source available (such as an AC
Adapter or charged modular battery), follow these easy steps: (Figure 17)
1 Have a charged battery ready to install.
2 Shut down your notebook.
■
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.

USING HEAVY CURRENT DEVICES SUCH AS A MODEM OR FREQUENT DVD/CD-RW/CD-ROM ACCESSES MAY
PREVENT CHARGING COMPLETELY.
