Could you not just turn off everything off at the mains socket when not using it, except perhaps the router - or even that too?
Or at least turn the things to face away from your bed if their lights are a nuisance.
Though they are not in my bedroom, my PC and printers are fed from a 4-way socket board plugged into one of a twin switched socket, the router PSU is alone in the other; so I can leave the router on as apparently advised but close the computer and turn off the supply to it and everything else. I also turn off my portable radios' leads at the mains since discovering their alleged On/Off switches are on the wrong side of the internal power-supply units.
I prefer fairly deep darkness and my bedroom is at times despite no curtains (it is not closely overlooked). I don't like it so dark I cannot focus on something if I awake, but nights where I live are rarely so dark I cannot see the sky as a pair of very slightly lighter rectangles. Heavy overcast glows slightly yellow by reflected street-light.
There is also a very faint bluish glow from a clock/radio next to the bed, facing somewhat away from me.
Facing South though, the room does catch the moonlight!
I prefer a small light of minimum but perceptible luminescence that originates from a fixed location---something whose location is known to me and by seeing which I can immediately orientate myself in the room.
Usually an un-curtained window is enough, even on the darkest, cloudless, Moon-less Winter nights.
I did once wake in some distress in an outdoor-pursuits club dormitory, totally disorientated because someone had innocently hung a blanket from a neighbouring bunk, blocking my view of the window.
I know the feeling! I have a small, wind-up l.e.d. lantern for finding my way; and a battery-operated cupboard light on the bathroom mirror. This is so I am not disturbed further by bright light.
