I have a problem with my windows 7 laptop automatically waking after I put it to sleep and then I find it later with the battery drained. I tracked down the culprit using the "powercfg -lastwake" command to be a Backup task in the "Windows Server" section of the task scheduler.

I have tried unchecking the "Wake the computer to run this task" checkbox for this task, but after I do this and reboot, the box is always rechecked again. How can I make this setting persist? I have full admin rights to this laptop, but it is on a domain.

Edit: I looked into the domain policy settings as suggested by Dave below and did not find any policies related to scheduled task settings. Any other ideas?

If there is a group policy coming from the domain that is enabling this setting, sometimes you can use the local group policy editor gpedit.msc to disable it and override the domain GPO. I have seem this work with other power settings.

Where will I find such a task policy if it exists in the gpedit.msc tool? I am not very familiar with the domain policies. Thanks! –  KyleL Oct 3 '12 at 12:54
you can run gpresult at the administrator command prompt to determine the group policy the domain is giving you. then rsop.msc to see the settings in the policy. –  Dave York Oct 3 '12 at 13:08
Based on the output from gpresult /r and rsop.msc I do not see any policies related to task settings. I will update my question to indicate this. –  KyleL Oct 3 '12 at 13:41

It turns out this was being enforced by Windows Small Business Server 2011 LaunchPad. In the launchpad application, there is a "Backup" option with a checkbox to auto-wake the computer.
