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.
