I just close my laptop because everything will still be there and I ain't got no time to wake up the next day and wait for it to turn back on and all. I always get so impatient.
I used to just close it, but then I got a virus and I had to basically destroy my computer and then rebuild it again. Now I just turn it off manually. Logging of is for *******.
I shut it down if I know I won't be using it for more than a few hours. So I shut it down when I go out, or go to bed, but only close the lid if I'm going to dinner or having a shower.
