Do they hibernate or go into a power save mode when not being used?
Time to Sleep
Sleep, which is the default power-saving state in Windows Vista, is a low-power state that preserves whatever you were doing in memory. A small amount of power is used to maintain that memory (typically less than 1 watt on a modern laptop).
It causes your computer to go to sleep automatically if you haven't used the system for a set amount of time. Of course, if you know you are stepping away from your computer, you can also choose to put it to sleep manually.
On most computers that are running Windows Vista, you can put the system to sleep simply by pressing the power button (on a laptop, you can also close the lid). This is the default setting on most computers. However, if you want to customize your experience, you can do this by using the Power Options applet in the

Screen savers were originally developed to save older monitors from damage by preventing the burn-in of pixels into the screen. Today, screen savers are mainly used to personalize computers or to protect them with passwords required after a certain amount of idle time.
Screen savers do not conserve energy. In fact, many of today's sophisticated screen savers use more energy than your computer would use under light conditions. Even when a display goes blank, many screen savers continue to run and consume energy. And some screen savers actually prevent your PC from going to sleep.
To increase the energy efficiency of your computer and make less of an impact on the environment, you should use display blanking instead of a screen saver. If you want the security of requiring a password to access the computer after the display has blanked, configure your PC to use the blank screen saver and check the box to display the logon screen on resume. The blank screen saver doesn't consume any more energy than an idle computer, and it allows your PC to go to sleep when the sleep idle timeout is
When most people think of sleep, they think of it as a relaxed but yet not a very important part of our daily lives. What most people don’t understand is although we are not up and moving around and getting tasks completed, our brains are still very active. Without sleep our bodies do not function correctly on a daily basis, and our mental state is at risk.
Room occupancy Monitoring: This will monitor that there is how many people in the room so that the amount of air and humidity can be controlled also if there is no one in the room then the lights will be automatically switched off.
Sleep is a state when the body’s senses and motor activity are disrupted resulting in total or partial unconsciousness (Nordqvist, 2010). As a result all all voluntary muscles are rendered inactive (Nordqvist, 2010). It is a period when the body produces new bone and tissue, resulting in the growth and repair of the body (Nordqvist, 2010). Typically sleep is defined in humans based on brain wave activity patterns and other physiological changes (Harvard Medical Institute, 2007).
Technology can disrupt people’s train of thought. To begin with, many people around the world use technology. Electronics can help students and also affect them in many ways, but whether or not shutting down all electronics can help. Schools should participate in “Shut Down Your Screen Week” because of many reasons.
According to the Oxford Living dictionaries, “Sleep is a condition of body and mind which typically recurs for several hours every night in which nervous system is inactive, the eyes closed, the postural muscles relaxed and consciousness practically suspended”. Sleep is necessary for all the human kinds be healthy and maintain daily activities. A lot of problems will arise if a person lacks energy or having some sort of disorder while sleeping. There are lots of problems were issued due to the insufficient sleep. John Tesh one of the prominent figures has raised the issue about weight gain because of a lack of sleep.
The exact purpose of sleep is still not fully understood but it is thought to be a state in which organisms can regenerate and further development in the brain. When humans get enough sleep, they feel more energized and refreshed. Sleep can aid the body in fighting off harmful infections. It can also decrease the risk of obesity and some heart and blood related problems. Sleep is a time when organisms are able to repair damaged cells and produce more energy through the process of cellular respiration. Without sleep, our bodies would not function properly and would eventually shut down.
Many phases and function of sleep are still under intense research, however judging from a simple fact - all animals do sleep, it is obvious that its role is indubitable. Nonetheless, many people are still having the mind set of sleep is merely a time-wasting-activity. Even among professionals who perform crucial roles such as doctors, teachers, engineers are willing to compromise their sleep, with a simple excuse, busy. In short, they are experiencing either acute total sleep deprivation or more common, chronic partial sleep restriction[2]. Many effects of both types of sleep deprivation were investigated, in particular health, attention, decision making.

Based on Laurel Nesbit, a program assistant in the Office of Sustainability here at UF, our campus manages to utilize 470,000 Megawatts of energy annually. This figure is generated from all the energy-consuming gadgets that operate on our campus on a daily bases. These gadgets include computers that are left turned on over the night even they are not in use, copiers, and the fume hoods in our laboratories. Admittedly, the success and the health of wellbeing of the students is contingent upon some of these equipment. For instance, the laboratories need the fume hoods in order to keep the experimenters safe. Instead of casting these necessities away, we can develop alternatives which will be capable of generating energy in order to compensate for the electricity that we endlessly
Sleep is a behavioral state characterized by little physical activity and almost no awareness of the outside world. Sleep is actually made up of two separate and distinctly different states called REM sleep (rapid eye movement) and NREM sleep (non-rapid eye movement). With NREM sleep it is further divided into stage 1-4 based on the size and the speed of the brain waves. Step one is the stage when you drift off to sleep or doze off. For example people doze off in class because you are bored and have nothing to do but listen to the teacher talk. Some parents may call it a cat nape when their kids go to sleep for about ten minutes or so. The second stage is called an intermediate stage of sleep. That is when

In March, 1998, students at Colchester Sixth Form College in Britain also tested the results of sleep deprivation. Certain functions were, indeed, slowed down, like typing skills. Speech became slurred and reaction time slower. However, much to their surprise, they discovered that there was an improvement in math skills, short term memory and the ability to sort papers.
Merriam-Webster’s dictionary defines sleep as the natural periodic suspension of consciousness during which the powers of the body are restored (sleep. 2016. In Merriam-Webster.com.). Sleep is an essential biological function with major roles in recovery, energy conservation, and survival. Sleep also appears to be important for vital function such as neural development, learning, memory, emotional regulation, cardiovascular and metabolic function, and cellular toxin removal. Sleep is universally experienced as a state of unawareness. It has been said that we spend approximately one third of our lives asleep. Rat studies have been conducted where total sleep deprivation leads to
Monitor radiation has been discussed throughout computer journals for years. I have learned that different monitors have higher or lower radiation levels. Monitors made overseas are generally considered to have a lower radiation level than those built in the United States. For example, as an engineer the Management Information Services (MIS) unit told us that NEC monitors had much lower radiation levels than IBM monitors. After sitting at a computer during my eleven-year career as a Civil Engineer with the Los Angeles Department of Water and Power, I often found that headaches at the end of the day were common. My eyes felt strained due to the looking at a monitor for an extended period of time. Over the years as an engineer I bought various types of glare screens for my computer monitor. Even though I doubt the glare screens help with the reduction of radiation given off by the monitors, they do seem to help with eyestrain.
