Connecting a Power Source

To determine the amount of time the battery lasts, see “Displaying Battery Information” in 
the online manual Customizing Your VAIO® Notebook. When the battery power is running 
low, both the battery and power indicators blink.
When the computer is directly connected to AC power and has a battery pack in the battery 
bay, it uses power from the AC outlet.
See “Using a Second Battery Pack” on page 46 for information on installing and charging a 
battery pack in the multipurpose drive bay.
Keep the battery pack in the computer while it is directly connected to AC power. The battery 
pack continues to charge while you are using the computer.
If the battery level falls below 10%, you should either attach the AC adapter to recharge the 
battery or shut down your computer and insert a fully charged battery.
You can extend battery life by changing the power-management modes in the PowerPanel 
The battery pack supplied with your computer is a lithium ion battery and can be recharged at 
any time. Charging a partially discharged battery does not affect battery life.
The battery indicator light is on while you use the battery pack as a power source. When 
battery life is nearly depleted, the battery indicator starts flashing.
For some software applications and some peripheral devices, your computer may not enter 
System Hibernation mode when the battery life is low. To avoid loss of data when using 
battery power, you should save your data frequently and manually activate a power-
management mode, such as System Suspend or System Hibernation.
