What is the purpose of switching to the red light?  To "power down" during critical situations?  Or is there a psychological reason (perhaps the red light helps people remain calm?)?

Its amazing how much guff there is about this question! As a naval officer, I have an idea as to the right answer - red is used because it is the longest wavelength of the visible spectrum and as such the eye is least sensitive to it.  If you were to stretch the wavelength a little more, you would be in the infra red band which is actually invisible to the human eye.  The reason red is used in the submarine control room (the bridge is on the top of the fin or sail as it is known in the US) is that when looking through the periscope, the officer-of-the-watch's eyes are accustomed to the darkness and do not have to re-adjust to achieve night vision which can otherwise take up to five minutes. He can therefore switch quickly between looking through the periscope and looking around the control room.  They can continue with white light in the daytime when it makes little difference.  On more modern submarines, optical periscopes are now being replaced with tv monitors and this problem will therefore be solved.  Its absolutely nothing to do with reminding people what time of day it is as submariners tend to do 6 hours on, 6 hours off, meaning that the time of day doesn't really matter!

while you shutting down the system... there may b some unwritten data on the ram of ur computer.. if u just turn off the power switch u will lose all the data on the ram.. coz ram is dynamic storage element!! it stores the data only when the power is on!! when u use shutdown it flushes all the unnecessary data and backups some system files on the pc in order to stablize the pc for next time boot up.  so it is necessary to use shutdown dailouge... hope this answer helps u!! bye dude!!

Yes because sometimes lighting can get through the electric lines and damage your PC if the building does not have proper "earthing".  Safer still, after turning off the computer, remove the plug from the socket too. Replug only after the storm has gone

Very interesting.  it sounds like the wiring leading to the power light or possiblely the battery could be the problem  \nif you can afford it replace the battery  (I recommend Lithiom Ion) (Li ion)

There is a piece of hardware in the back of the computer called a Power Supply. It converts the electricity from the wall into something the computer can handle. The Power Supply also has a off switch. If you hit that all electricity ceases to your computer, thus making it impossible for the computer to turn on. When that light is on it means the computer is receiving electricity.

If you read the book "Einstein's Dreams"  you would understand that for every decision you must make in this time and place there is an exact parrallel universe which you make the opposite decision.  So you may of missed the boat here but you didn't miss it there. \n\n***My own personal oppinion.  We are all here for a purpose, not always a big one.  It could be something small as to run a stoplight and cause a cop to have to pull over one more person that day or to smile at someone to brighten a really bad day.  All this stuff seems small but if you step back and look at the big picture..You just made that cop 15 minutes later possibly preventing him from pulling over a drug dealer or someone dangerous.  Maybe the person you smiled at thought the world was against them and was contemplating suicide and looking for one little sign there was someone out there....Its the chaos theory but I believe it has purpose.

No need to turn it off DUH!!!  LOL!  Everyone has "brain farts" :)

HMM.  Maybe if you turn on switch A and leave it for about 2-3 minutes. Then turn it off.\nThen turn on switch b and head upstairs.\nThe light controlled by switch b will still be on.\n\nThe light controlled by switch A will be off but still warm to the touch.\n\nThe light controlled by switch C will be cold.\n\nThink that will do it?

first. hollywood, dramatic effect\nsecond, cops use flashlights so that if there is a burgalor and he is trying to catch the cops or hurt them (or something of that sort) then they use flashlights because the robber would see a bright light in a dark place, so it would be nearly impossible to hit the cop. (In real life, cops use a flashlight that blinks so the robber would see a light and then itd go away and he wouldnt know where to shoot. [think of a firefly])\nCSI .. some good stuff. ..

Some lights are on a timer to save electricity.

Depending on how much you "strain" your computer, the RAM will get more and more fragmented thus the performance will get worse.\nIf you don't need your computer running at night time, shut it down! This will save energy and spare the components.\n\nThere is still a common misbelief that turning the computer off and on will lead to a higher power consumption caused by the boot process. Not with todays computers!

That's so true....quite an enigma! I always say my dad gets up to turn on the traffic lights......you'd think now that they've retired they would sleep in, but no, it's up at the crack of dawn.....really, really weird...♥

Depending on what operating system you are running, it could have shut down automatically, although it sounds like this has never happened before.\n\nHave a pet, child or partner that might have accidently hit the power or reset button?  When the computer is shutting down, then it usually is because one of our children hit the reset or power button.

Yes, slow down...but be sure to allow them to pass.  I've also found it helpful to turn on my emergency flashers.  It gets their attention without your having to do much.  \n\nWhere I live it's not the best idea to flip someone off while driving.  Danger Will Robinson!

There is a lot of factors that could go wrong, so if you are really worried about it, you should probably shut down.  Surge protector, properly grounded electrical system, and other factors will make it less risky though.  It may be worth the risk.

The 'apple' as you call it is actually a combination of two symbols. The | that represents power on and the O that represent power off. When joined to make the 'apple' it represent one switch to do both.\n\nI hope this helps.

It's actually normal.  I know that if some people stare into flashing lights (kinda like a strobe light)  it can make them go into seizures. it has something to do with the brain and the light, I am not real sure what could cause it maybe it is the motion of the light and the brain not being able to process it fast enough.
