❑

To determine the remaining battery charge, see “Displaying Battery 
Information” in your online user guide for more information.

❑

Keep the battery pack in the computer while it is connected to AC power. 
The battery pack continues to charge while you are using the computer.

❑

If your battery level falls to less than 10 percent, 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 utility. See “Using Power Saving Modes” in the VAIO® 
Computer User Guide.

❑

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 is on while you use the battery pack as a power source. 
When battery life is nearly depleted, the battery indicator flashes.

❑

Your computer may not enter Hibernate mode when the battery life is low, if 
certain software applications are active, or if certain peripheral devices are 
connected. To avoid loss of data when using battery power, save your data 
frequently and manually activate a power management mode.

✍

You may lose data if you remove the battery pack while the computer is on and not 
connected to the AC adapter or if you remove the battery while the computer is in a 
power saving mode.
