## Battery

  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.

- Changing the Rapid Wake (Sleep Mode) Settings

  You can change the Rapid Wake settings in VAIO Control Center.

- Charging the Battery Pack

  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.

- Extending the Battery Life

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

- Charge Indicator Status List

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