How This Book Is Organized

This manual contains the following chapters and appendixes:

Chapter 1, Introduction to Power Management, describes the value of reducing power consumption through Power Management features and provides an overview of how those features can be used.

Chapter 2, Power Managing Displays, describes how to use desktop software features to turn off power to the display monitor when that device isn't in use.

Chapter 3, Managing System Power, describes the features that enable a desktop system to power off automatically when not in use. This power saving method is made practical by using the Suspend-Resume feature, which can record the system's current state when it is powered down, and then return it to that state when powered up again.

Appendix A, Configuring Power Management Using the Command Line, describes a way to configure Power Management features through the pmconfig command and the power.conf file. This appendix also explains how to change the idleness definition by editing the power.conf file.

Appendix B, Troubleshooting, explains how to respond to various problems and error messages related to Power Management software.
