Deploying a lot of software post image, tips to keep machine from sleeping?

Does anyone have creative ways to keep machines from going to sleep during deployment if they're deploying a lot of software post image?  Perhaps script sleep settings at the beginning of the job?  I was building in restarts but that just seems like a bad way to do it since it takes so long for the agent to start up on the delayed start to pick back up on the job list.

Our sleep settings are set via AD, but I could arrange the deployment job so that joing to AD happens at the end.

Thanks for any ideas.

I'm on CMS 8.1 latest RU.  Will jump to 8.5 once a few updates are released for it in the coming months.
