# Using Hibernate Mode

In Hibernate mode, the current state of your VAIO computer is saved to the built-in storage device, and then the computer is turned off. Hibernate mode is useful when you do not intend to use the computer for an extended period of time.

## To activate Hibernate mode

1. Click (Start), (arrow) next to the Shut down button, and Hibernate.

Hint

- The following operation also places your VAIO computer into Hibernate mode.

- Press the Fn+F12 keys.

- The power indicator light is off while your VAIO computer is in Hibernate mode.

## To return to Normal mode

1. Press the power button.

Note

- Note that if you press and hold down the power button for more than four seconds, your VAIO computer will turn off automatically. Doing this will erase all unsaved data.

- 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.

- Before moving your VAIO computer, make sure that the power indicator light is off to avoid impact or vibration to the running hard disk drive.

Hint

- When the charge and power indicator lights blink concurrently, or a low battery message appears, place your VAIO computer into Hibernate mode or plug it into an AC outlet.
