In previous releases, it was necessary to start the Dtpower software as superuser to edit the configurations. In this release, the program can be started in a number of ways, all of which allow you to change the configurations.
If you are unable to access Dtpower for editing purposes, it may be because you do not have the correct permissions. See the dtpower(1M) man page for details.
If Dtpower is already running, it may appear on your desktop as this icon:
On the CDE desktop, hold down the menu button on your mouse.
From the pull-down list, select Tools.
From the pull-down list, select Power Manager.
From the front panel on the CDE desktop, select Applications Manager.
From Applications Manager, select Desktop_App.
From Desktop_App, select Power Manager.
Due to system initialization, Dtpower can take some time to launch.
Every Dtpower window has one or more of the following buttons:
A triangle indicates a pull-down menu. In the Figure 2-2, the Current Power Saving Scheme box can be pulled down to reveal two additional levels of power management: Minimal and Disabled.
OK puts into effect the settings currently displayed in the window.
Cancel reverses settings to the state they were in when OK was previously selected (or to default values if this is the first time you have run Dtpower). Cancel, however, will not return to earlier values if you have already selected OK.
Less reduces the window to conceal the options revealed through the More button.
Edit is located in the Quick Edit tab (see Figure 3-2). It opens a window in which you can configure the AutoShutdown and AutoWakeup options.
The simplest way to select a level of power management for your system is to choose one of the preset power saving schemes. The schemes appear in the Current Power Saving Scheme box in the Dtpower basic window. The default scheme is Standard, as shown in Figure 2-2.
The implementation of the power saving schemes depends on the architecture and the Energy Star capability of the hardware running Dtpower. The following sections describe the power-saving schemes that are available.
The implementation of the power schemes depends on the power saving capabilities of your hardware. In addition to the schemes described below, you can also modify any one of these schemes and save it as a Customized scheme. For more information on creating a customized power saving scheme, see Chapter 3, Customizing Power Schemes.
The default Power Management settings of your hardware determine the implementation of the Standard scheme. (To determine your system's default settings, see Chapter 1, Introduction to Power Management.) SPARC platforms that are Energy Star 3.0 compatible, for example, reduce power consumption by entering a power-saving mode for all devices.
Manages power for monitors only. The monitor goes into power-saving mode after 30 minutes of idleness; no other devices are power managed.
No power management. None of the components of the system are power managed.
This launches the Dtpower basic window.
From the pull-down list in the Current Power Saving Scheme box, choose a scheme.
