acpitool -S  =>  suspend to disk (hibernate)  =>  Puts machine into S4.
acpitool -s  =>  suspend to ram (sleep)         =>  Puts machine into S3.

man acpitool

Putting the machine into S3 is problematic for several HW.  In several
cases HW goes to S3 OK, but it has trouble coming back.  That wouldn't
be much of a problem unless the HW is your video card, :-)

There are multiple ways to do the same thing, there are the pm-* tools
as well, and several other ones.  I just prefer using acpitool, which
I have for years...
