## Battery

- Charge Indicator Status List

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

- Notes on an Extended Battery Pack (Extended battery pack supported models)

  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).

- Extending the Battery Life

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

- 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.

- Checking the Battery Charge Capacity

  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.
