Using Power Management


Using Power Management describes how to configure and operate workstations to conserve energy using the Power ManagementTM software provided within the Solaris(TM) operating environment. The software for managing system power is not intended for use on server computers; however, techniques described in this manual for managing power for a display connected to a server computer may be of value.

This manual describes how to use Power Management features on workstations produced by Sun Microsystems, IncTM. If you are using this Solaris release on hardware supplied by another manufacturer, refer to information sources for those products to determine whether this Power Management software can be used with your hardware. Also refer to your hardware manufacturer's documentation to determine which distinctions within this manual (such as between machines with sun4m and sun4u architectures) apply to your hardware.

How This Book Is Organized

This manual contains the following chapters:

Chapter 1, Introduction to Power Management describes the value of reducing power consumption and provides an overview of how Power Management features can help achieve that goal.

Chapter 2, Basic Dtpower Settings and Configurations gives an overview of the Dtpower graphical user interface (GUI), its conventions, and basic power saving schemes.

Chapter 3, Customizing Power Schemes describes how to create a customized power saving scheme by overriding the schemes for system, monitor, and disk drive power.

Chapter 4, Using the Suspend-Resume Feature discusses the ramifications of using Suspend-Resume on ongoing system processes and issues that should be considered before choosing this feature. It describes the power off and power on features, as well as ways to save your system state when you power down and resume in the saved state. It also explains how to respond to various problems and error messages related to the Suspend-Resume feature.
