Power management commands
The PowerPanel™ utility also provides power management commands that you
can use to activate specific power management functions and to control power
for a specific device. You can use these commands to override a profile setting or
initiate an immediate action.
Conserving battery power
When using the notebook with a battery, the LCD display and the hard drive can
be set to switch off automatically to conserve battery power.
See “Power Management profiles” for more information.
Icon Description
Standby
Puts the system into Standby mode, a power management state that
saves the state of the system and peripheral devices in memory
(RAM). Power consumption reduces to a minimum, and the system
remains on. To return the system to the active state press any key.
Hibernate
Provides for the lowest level of power consumption. The system
writes the state of the system and peripheral devices to the hard disk
and turns off the system power. To return the system to the original
state, use the power button to turn on power. The system saves the
data in the Save to Disk Partition on the hard drive.
