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.
Presentation 
– 
Keeps the display on at all times while it conserves 
power. This option is ideal for slide show presentations. You can 
establish settings for LCD (Video) Standby, Hard Disk Sleep, and 
System Suspend to optimize power management for your system.
Word Processing 
– 
Optimizes power management with longer 
timeouts on the hard disk and display screen. You can also establish 
settings for LCD (Video) Standby and System Suspend to optimize 
power management for your system.
Communications 
– 
Extends battery life by initiating a quick display 
timeout. The Internal modem remains powered. You can also 
establish settings for LCD (Video) Standby and System Suspend to 
optimize power management for your system.
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, 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.
