Dumb question

if you want to save electricity unplug it otherwise don't worry about it and leave it on.
secondly there is no such thing as a dumb question , on the contrary... dumb people ask no questions.
 
I have all of my devices plugged to a surge protector and every night before I go to sleep first i turn them off from the remote then the back switch if any and finally I turn off the swich from the surge protector just in case we get a lightning over the night and to protect them from being burned out and I believe this the safest way.
