           Allow the system to enter sleep states in which main memory is
           powered and thus its contents are preserved, such as the
           suspend-to-RAM state (i.e. the ACPI S3 state).

           Enable the suspend to disk (STD) functionality, which is usually
           called "hibernation" in user interfaces.  STD checkpoints the
