Remember to shut down Lenovo S12

I found that merely putting my Lenovo S12 netbook to sleep isn't going enough to keep it down.  It will, in most case, auto awake itself, and since it's running that damn face recognition authentication system, it will keep the S12 staying up forever.  So the best way to put the machine into energy efficient mode is to shut it down.

And speaking of that face recognition feature, it is such a bitter sweet.  Cause for one hand it's actually working pretty OK, but I hate it keeping my machine running, and thus render sleep mode unless.
