I wonder why all of the display backlights are on? I understand having the laptops open to stop them going to sleep without an external display, but I'd've thought you could turn the backlight all the way to "off".

You can even disable sleep with closed lid[1], but addmiteddly that might intefere with ventilation, since there are vents in front of the hinge.

Perhaps the light is on so that they can spot dead devices at a glance?
Yeah perhaps, but I'd've thought some software mechanism (regular pings etc) would be easy enough to offset the power / heat of having the backlight on. Although I guess backlights are just a few LEDs these days, so probably actually not too bad to keep on.
Maybe it's just that it makes a cooler photo.
