Extending the Battery Life
When your VAIO computer is running on battery power, you can extend the battery life using the following methods.
-
Use the power saving mode. [Details]
When you do not need to use your VAIO computer temporarily, you can use either Sleep mode or Hibernate mode.
To extend the battery life, use Sleep mode frequently. If you do not intend to use the computer for an extended period of time, use Hibernate mode. For longer breaks, turn off the computer.
Resuming the computer from Hibernate mode is faster than from booting up the computer, and Sleep mode, even faster than Hibernate mode.
-
Decrease the LCD brightness of the computer screen. [Details]
-
Turn down the volume of the speakers and headphones. [Details]
-
Disconnect peripheral devices that are not in use.
