The battery pack is consumable. The capacity gradually declines through repeated cycles of recharging and discharging. As a result, the battery life becomes short even if it is fully charged and eventually the battery pack reaches the end of its life.

The battery pack can be charged even while you are using your VAIO computer when the computer is connected to a power source. The charging time may vary depending on operating conditions.

The charge indicator light turns on or blinks differently according to conditions.

When your VAIO computer is running on battery power, you can extend the battery life using the following methods.

You can change the Low Battery Hibernation settings in VAIO Control Center.

You can change the Intel Smart Connect Technology settings in VAIO Control Center.

This topic explains battery charging behavior when an extended battery pack (not supplied) is attached to your VAIO computer in addition to the installed battery pack (the primary battery pack).

Sleep mode enables you to take a break and retain the computer’s state, including data you are working on.
