The apmsleep command is to put the computer into a standby or repair state. Some computers, especially laptops, can use real-time clock (RTC) chips to wake up from low-power pause mode to DRAM mode. Apmsleep can be used to set the alarm time in RTC and enter pause or standby mode. An interruption from RTC caused the computer to wake up. The program detects this event by waiting for a transition in kernel time and terminates successfully. If no time transition occurs within one minute, or if an error occurs, the exit value will be non-zero.
