Power Management Commands
PowerPanel also provides power management commands that you can
use to activate specific power management functions and to control
power for a specific device. You might use these commands when you
want to override a profile setting or initiate an immediate action, such as
putting the system into Video Standby mode before the Video Standby
timer expires.
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.
For details, see Power Management Profiles on page 4.
Icon Description
System Idle
Puts the system into System Idle mode, a state of low
power consumption. This state stops the CPU clock and puts all
peripherals into low power mode. To return the system to the active
state, press any key or power switch on your system.
System Suspend
Puts the system into System Suspend 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 or the power switch on your
computer.
System Hibernation
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 switch to
turn on power. The system saves the data in the Save to Disk
Partition on the hard drive.
LCD (Video) Standby
Turns off the LCD to save power. If you
turn off the Video Standby timer in the AC Power-Profile Editor,
the display remains active except when the system enters System
Suspend mode. The video display system is one of the largest
consumers of power in the system.
