In previous versions of Ubuntu (16.04) it was possible to set an automatic suspend on laptop lid closure when the laptop was battery powered, but not when on mains. This is no longer available; automatic suspend provided by the power control panel is purely time-based. The gnome tweak tool does offer a lid-based suspend trigger, but this is independent of power source.
