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). Power consumption is reduced
to a minimum. 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. Power consumption is reduced
to the lowest possible setting without being completely off. 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 software 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. Slide the power switch to the right to return to normal mode.
If the computer does not activate Hibernate mode, see Frequently asked questions for more information.
