We have two workstations for CAD work and one for our CAD database. We noticed that when we make a workflow transition in PDM, workstation goes to sleep. We have it set for half an hour. Is this normal and how can I tweak WIndows 7 power settings so that also with longer state transitions none of the workstations goes to sleep. I don't want to disable sleep option. Is there any reason why this happens, even that workstation is "working".
