The System Panel

On the System panel you can specify the conditions when your system will shut down automatically while idle.

Be sure you have read all cautions on using Power Management software in Using Power Management and in release notes before changing the AutoShutdown settings.

AutoShutdown uses the Suspend feature to automatically power off your system. When the system powers up again, it will resume in the same state as when it was suspended.

Using the System panel of the dtpower window, you can activate or deactivate the AutoShutdown feature, and specify the following times:

• The number of minutes of idle time before AutoShutdown attempts to suspend the system

• The Start and Finish times of the period each day when AutoShutdown can occur (When the Start and Finish times are identical, AutoShutdown can occur at any time.)

To Set an Idle Time for AutoShutdown of the System

1. Start dtpower as superuser (see "Starting dtpower").

2. Drag the Suspend slider to the number of minutes of idle time you want before the system will power down automatically.

   If you want to completely deactivate the AutoShutdown feature, select the Never setting at the far right of the slider.

   Also, you can type the number of minutes directly in the numerical box to the right of the slider.

3. Select the Start time of the period each day when you want AutoShutdown of the system to be able to take place.

   You can select the time (in 15-minute increments) through a menu that drops down from the button closest to the Start label.

   Also, you can type the Start time directly into the numerical box.

4. Click AM or PM for the Start time.

5. Select the Finish time of the period each day when you want AutoShutdown of the system to be able to take place.

   You can select the time (in 15-minute increments) through a menu that drops down from the button closest to the Finish label. The last setting on this menu is All Day, which means AutoShutdown can occur at any time of day.

   Also, you can type the Finish time directly into the numerical box. You can specify "All Day" this way by entering a Finish time that is identical to the Start time.

6. Click AM or PM for the Finish time.

7. Click the Apply when the settings you want are all displayed.

   If you want to reject the displayed settings, select Reset and the currently active settings (that is, whatever settings were last put into effect by selecting Apply) will be displayed in the window.

In Figure 3-6, the System panel is set for AutoShutdown of the system after 60 minutes of idle time between 7:30 pm and 9:00 am
