NAME

       s2ram - program to suspend to ram (suspend)

SYNOPSIS

DESCRIPTION

       This manual page documents briefly the s2ram command.

       s2ram is a program that will suspend your system to ram (put it in S3 mode). Which means
       that the system is in a lower power mode. It asked to do so it will wake up farely
       quickly. However, if the system will run out of energy entirely you will lose data. That
       is why it is recommended to use s2both(8) s2ram is only provided to find out any work
       around needed to make suspend to both work. See README.s2ram-whitelist and README.Debian
       for more information.
