Using power saving modes

In addition to the normal operating mode, which allows you to turn off specific devices to save power, your computer has
two distinct power saving modes: Standby and Hibernate. Use the Standby and Hibernate power saving modes to override
a power profile setting and initiate immediate action.

Standby — Saves the state of the system and peripheral devices in memory (RAM). The system remains on, and the
computer screen (LCD) is off.

Hibernate — Saves the state of the system and peripheral devices to the hard disk. Hibernate mode consumes the
lowest level of power. Your computer enters Hibernate mode when the remaining battery charge drops below 5
percent, regardless of the setting you select.

Since some programs and peripheral devices prevent the system from entering Hibernate mode, save your data

frequently to avoid data loss.

To activate Standby mode

1.

Press the Fn and Esc keys. The power indicator blinks in this mode.

2.

Press any key to return to normal mode.

To activate Hibernate mode

1.

Press the Fn and F12 keys, or press the power button and release it immediately. Do not move the computer
until the power indicator turns off.

2.

Press the power button to return to normal mode.

If your computer does not activate Hibernate mode, see

for more information.
