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. You can 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 in the Save to Disk Partition 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 with the remaining battery charge drops
below 5 percent, regardless of the setting you select.
Some software programs and peripheral devices prevent the system from enabling Hibernate mode when battery
power is low. You can manually activate a power management mode to conserve power, but you should save your data
frequently to avoid data loss.
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 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 the computer does not activate Hibernate mode, see Frequently asked questions for more information.
