Power Management(TM) software increases your system's energy efficiency to meet the U.S. Environmental Protection Agency (EPA) Energy Star guidelines. Power Management conserves the amount of power that your system consumes. Power conservation is done in two levels:
  • The first level reduces the power consumption of each system component when possible. Any system component that is power manageable can be placed in a low power-mode; one example is the display monitor.
  • The second level removes system power completely when the system is not in use. This feature, named AutoShutdown, makes use of the Suspend-Resume feature to allow for quick restoration of the system during the next power on.
The Power Management software consists of two utilities:
  • dtpower
  • Suspend-Resume

Suspend-Resume

Suspend-Resume is a new, time-saving feature in the Power Management software that allows you to power cycle your system without losing the state of your current activities. Your workspace and files are preserved when the system is powered off so that they can be restored to the same state when the system is powered on.
For example, you can be in the process of editing a document when you decide to leave and power off your system. By using the Suspend-Resume feature, your edit session will automatically be restored and appear as it did when you left it the next time you power on the system.

dtpower

The Power Management graphical user interface, dtpower, allows you to designate periods of inactivity after which the display will turn off and the system will shut down. You can also use this tool to set the time of day to activate the automatic shutdown; for example, if you wish to use this feature only after your regular work hours.
