Suspend mode on Raspberry Pi 2

    Is there a suspension mode for the Raspberry? I did not find anything except this.

    1. Go to Configfiles\sleep.conf.d (in Windows) or /storage/.config/sleep.conf.d (over SSH).
    2. Rename sleep.conf.sample to sleep.conf
    3. Open sleep.conf and remove this line: SuspendMode=false
    4. Reboot, enjoy.

    It does not help.

    Is there a suspension mode on libreelec?
