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 programs and peripheral devices prevent the system from entering Hibernate mode, save your data frequently to avoid data loss.
To activate Standby mode
1.Click the Start menu on the Windows® taskbar, and click Turn Off Computer.
2.Click Stand By.
3.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.
