Right-click the task for which you want to set power management options, and then click Properties.
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.

Notes

To perform this procedure, you must be a member of the Administrators or Server Operators group, or have been delegated the appropriate authority, on the local computer. As a security best practice, consider using Run as to perform this procedure.
XOX
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.
The Wake the computer to run this task check box is only displayed on computers that support it.
