Can someone please explain to me when I should use sleep and when I should use hibernate?  I have found some conflicting recommendations within the various help screens in my computer and am not sure of the best plan.  Is it true I shouldn't shut it down at the end of each day? 

 

I use my laptop as my primary computer.  I have 2 babies, so I use it for a few minutes here and there throughout the day.  I do use it every day.
