Frequently asked questions
Using power saving modes
In addition to the normal operating mode, which allows you to turn off specific
devices, your computer has two distinct power saving modes: Standby and
Hibernate. Use the Standby and Hibernate power saving modes to override a
profile setting or initiate an 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 on 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.
To activate Standby mode
1 Press the key combination Fn + Esc . The power indicator blinks in this mode.
2 Press any key to return to Normal mode.
To activate Hibernate mode
1 Press the key combination Fn + F12 or 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.
✍
Some software programs and peripheral devices prevent the system from entering
Hibernate mode. If you are using a program that prevents the system from entering
Hibernate mode, save your data frequently to avoid data loss.
