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.
Word Processing – Optimizes power management with longer
timeouts on the hard disk and display screen. You can also establish
settings for LCD (Video) Standby, Hard Disk Standby, and System
Suspend to optimize power management for your system.
Spreadsheet – Optimizes performance and power requirements for
spreadsheet applications such as Microsoft Excel. ®
Communications – Extends battery life by initiating a quick display
timeout. The Internal modem remains powered. You can also
establish settings for LCD (Video) Standby, Hard Disk Standby, and
System Suspend to optimize power management for your system.
Automatic Profile Selection – Automatically switches to a profile
suitable for active applications.
Icon Description
System Idle – Puts the system into 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.
