Which software are you using? MassLynx or Empower or something else?
At the bottom right of the window, click on Shutdown disabled (or click on whatever message is there).
In Shutdown tab, you can Enable startup before batch or Enable shutdown after batch.
You can also choose Shutdown if queue is in pause and Shutdown time.
In Auto control tasks tab, you can configure startup or shurdown job.
Hope this helps.
