This command requires the Advanced Power Management subsystem. If run without arguments it reads /proc/apm and presents the output in a human-readable format.

Given a −S or −s option it requests that the machine be put into the APM standby or the APM suspend state, respectively. For a brief description of these states, see apmd(8).

Request that the machine be put into the APM standby state.
