@Luke2752 This might be a really obvious comment and you probably already know that the unit has to go to sleep after you switch everything off and close the doors, if you don't close it all down it can't go to sleep. After giving it time to go to sleep (light goes out) , you can get on with the rest of what you wanted to do.
Excuse the vagueness but I've been up to my eyeballs in advisory work these last few weeks and my brain is a ball of cotton wool.
@tomcat59alan will be able to tell you more about how long the system takes to go to sleep, when he gets his internet privileges back. Although he may find it hard to type
