## About Power Saving Mode

Your VAIO computer has power saving modes to conserve power while you are not using the computer in addition to the normal operating mode.

#### Sleep mode

In Sleep mode, all unnecessary devices of your VAIO computer are turned off, though some devices stay on to retain the computer’s state including data you are working on. Sleep mode is useful when you take a short rest, for example.

#### Hibernate mode

In Hibernate mode, the state of the current system is saved to the built-in storage device and your VAIO computer is turned off. Hibernate mode is useful if you do not intend to use the computer for a while.

#### About restart time and power consumption

The restart time from Sleep mode is the shortest, but your VAIO computer in Sleep mode consumes power the most. When the computer is off, the time you take to start the computer is longer than to resume it from power saving modes, but the computer can conserve power.

#### Note

- By default, your VAIO computer automatically enters Hibernate mode when the battery pack becomes weak. However, depending on the currently running software and connected devices, Windows may not allow their tasks to be suspended, resulting in failure to enter Hibernate mode. If this occurs and the battery pack is running out of power, the computer will be turned off, resulting in loss of unsaved data.

  While the computer is running on battery power, save data frequently and manually place the computer into Hibernate mode, if necessary.
