.SH "NAME"
s2ram \- program to suspend to ram (suspend)
.SH "SYNOPSIS"

.SH "DESCRIPTION"
.PP
This manual page documents briefly the \fBs2ram\fR command\&.
.PP
\fBs2ram\fR 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 \fBs2both\fR(8) \fBs2ram\fR 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\&.
