Vista - Power Management Schedule Task Options

I have created a script shelling out to schtask.exe to create
scheduled tasks on all my servers (1000+), which are all located at different
sites around the country. As you are aware the default Power Mgmt.
setting on the Settings tab is for "Don't start the task if the
computer is running on batteries" and "Stop the task if battery mode
begins" to be checked on I need to change the default Power
Management settings that are on the Settings tab in the scheduled job
through a script. Can anyone recommend a way to do this, and possibly
provide some sample scripting.

Thank you!
