--- Comment #1 from Elio <elio.martinez.monroy at intel.com> ---
S4 is called using the following instructions :

#!/bin/bash


cat /sys/power/state | grep disk
if [ $? -eq 0 ]; then
    date
    sleep 10
    # Clear old alarm
    echo '[CMD]echo 0 > /sys/class/rtc/rtc0/wakealarm'
    echo 0 > /sys/class/rtc/rtc0/wakealarm
        RC=$?
        if [ ${RC} -ne 0 ]; then
                check_rc "[CMD]echo 0 > /sys/class/rtc/rtc0/wakealarm" ${RC}
                return 1
        fi

    echo '[CMD]echo +40 > /sys/class/rtc/rtc0/wakealarm'
    echo +40 > /sys/class/rtc/rtc0/wakealarm
        RC=$?
        if [ ${RC} -ne 0 ]; then
                check_rc "[CMD]echo 40 > /sys/class/rtc/rtc0/wakealarm" ${RC}
                return 1
        fi

#    to change to /sys/class/rtc/rtcN/wakeup in future kernel
    dmesg -c >> dmesg
    echo '[CMD]echo disk > /sys/power/state    #S4'
    echo disk > /sys/power/state    #S4
    dmesg -c >> dmesg
else
    echo '[NOTE][CMD] S4 is not supported'
fi

echo "[CMD]suspend_resume end"
