Idle Time Optimizer off...

Hi all,

In my Norton's Administrative Settings, the Idle Time Optimizer is turned off. I understand the default settings would have it turned on, but I do not recall having changed it, and if I did it, I forgot what may have lead me do do it. I seem to have a vague reminiscence about something having to do with the type of system drive installed (I have an SSD). Does this make any sense, at all? Should I keep it as it is or should I rather move the slide to ON?

Please help.
