To set power management options for a scheduled task
1. Open Scheduled Tasks.
2. Right-click the task for which you want to set power management options,
and then click Properties.
3. On the Settings tab, under Power Management, do one or more of the
following:
* To conserve the battery power of your computer, select the Don't start
the task if the computer is running on batteries check box.
* To stop the task if the computer starts running on battery power,
select the Stop the task if battery mode begins check box.
* To wake your computer to run a task if the computer is running on
battery power, select the Wake the computer to run this task check box.
(This option is only available on computers that support it.)
Notes
* To open Scheduled Tasks, click Start, point to Programs, point to
Accessories, point to System Tools, and then click Scheduled Tasks.
* By default, power management is set to refrain from starting scheduled
tasks if the computer is running on battery power. If you are using a
portable computer that runs on batteries, and you want a scheduled task to
run, clear the default check boxes.
* If the power is interrupted or if the battery fails, the scheduled task
that is running might not complete.
