Perhaps not when I was actually asleep, but when I am trying to get to sleep? Or trying to get back to sleep? Yes. I had to change one phone for just that reason - the "you have had a call" LED was too bright at night.
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

And that's what I don't understand. In a dark room with your eyes closed, can you tell if a single LED is on or not? If you can tell, you must have really sensitive eyes, If you can't tell, what difference does it make?

It's possible he is rural, like me. Outside the house it is dark. Inside the bedroom it is dark. Except for that lone LED, which glows, ever brighter, and brighter, as your eyes adapt to the dark.... It is annoying - that's why all my computer equipment is switched off at the mains at night - the NAS, the PC, the router - those LEDs mount up!

The rurality of his location is irrelevant. I just can't believe that with his eyes closed, he could tell if an LED was on or not. Could you? Also, regardless of location, it isn't always dark when you are asleep. What about clear skies and a full moon? Or dawn on 21 June?

While sleeping....hmmmmmm Why not just turn it round so you can't "see the lights while you are fast asleep"
He took it all too far, but boy could he play guitar!

Oh god! I'd forgotten the XBox 360! Until it died for the second time, the LED on the power supply was ridiculously bright - you could land planes with the damn thing!

Doh, yes forgot all the associated power supplies.

Or perhaps yours are not very sensitive? :laugh: If it didn't make a difference, I wouldn't have mentioned it (nor would the OP, I suspect).

Well, that's possible... But if you had your eyes closed, and I illuminated a single, normal LED, you could tell?

This is getting a bit Zen: "Is an LED bright if no-one is looking?" :laugh:

Some of those leads are like bloody searchlights. When we go home to the country it is astonishlingly dark at night. In the middle of Singapore you can almost read by the ambient light!
Never underestimate the power of human stupidity RAH

I wonder when they are going to start making laptops with a switch that turns off all those annoying lights (power indicator, hard drive reads, network activity, and so on). Sure would be nice when watching a movie in a dark room or when you want your laptop on while you are sleeping. Any of you hardware manufacturers out there... I hope you're listening.
Get a MacBook...no annoying lights like that... The only illuminations are the screen, backlit keyboard (some models, can be turned off) and the sleep indicator (an LED that shines through a set of tiny holes and 'breathes' when the laptop is sleeping).
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p CodeProject MVP for 2010 - who'd'a thunk it!

When the alarm on my mobile goes off in the mornings I can see the change in brightness when the screen comes on, even with my eyes closed. I have to put something in front of my alarm clock too in order to make the room dark at night. Lights in a room at night can cause developmental problems in children including short-sightedness IIRC, and disrupts their sleep. Humans evolved in very dark nights, it makes sense to keep them that way.

True - there weren't too many streetlights 50,000 years ago - but the moon was still up there, and as you move further from the equator, you get longer and shorter nights throughout the year. Humans haven't evolved in environments where it is always dark for as long as they are asleep.

I have a big, round switch, that comes separately -- it's labeled "Duct Tape".

More than that. There's mounting evidence that artificial light at night screws up you melatonin production, and melatonin levels are among other things linked to the efficiency of your immune response. If you want a warm and fuzzy to go with that, the peak response level for diurnal effects in humans/animals and the peak in the most energy efficient (blue tinted) LED lighting often being installed for streetlights/etc are a very close match to each other.
