Nosleep 1 1 – Prevent Computer Sleep Through The Night

When you sleep, your body cycles through different sleep stages: 1, 2, 3, 4, and rapid-eye movement (REM).(Some schools of thought lump together stages 3 and 4.) The. I didn't think that was needed, and that the Policy settings were enough to prevent a computer from going to sleep. There is no UPS connected. Before Windows 10, we would manually configure the settings in Windows 7 for each user that needed to remote in when deploying their computer. This is the first time we are doing this through a GPO. Sleep deprivation worsens next-day pain,' Dr. Tingling, numbness, or pain in the hands and feet can cause frequent waking. Chronosync 4 9 4 x 2. Loud snoring and brief awakenings during the night may be signs you have sleep apnea, which causes brief pauses in breathing at night and leads to daytime sleepiness.

Probably one of the main reasons that babies who don't sleep through the night are such a big issue is that parents don't have realistic expectations of the sleep patterns of babies. Babies were designed to wake up often at night to feed and cuddle, and keep in mind that many adults wake during the night, too. If our expectations for babies were not so different from our babies' expectations for themselves, much of this 'problem' might disappear.

Following is information on studies that have been done on the typical sleep patterns of babies and young children.

The relationship between daytime exposure to light and night-time sleep in 6-12-week-old infants.
J Sleep Res. 2004 Dec;13(4):345-52.

Abstract: This project investigated the relationship between exposure to light and 24-h patterns of sleep and crying in young, healthy, full-term babies living at home and following a normal domestic routine. Measures included an ankle worn activity monitor, an external light monitor and the Barr Baby Day Diary in which parents recorded periods of sleep, crying, feeding and other behaviours at 5-min intervals throughout the 24-h period. Fifty-six babies (26 males and 30 females) were monitored across three consecutive days at 6, 9 and 12 weeks of age. There was an early evening peak in crying which was associated with reduced sleep at 6 weeks. Across the trials there was a gradual shift towards a greater proportion of sleep occurring at night. Sleeping well at 6 weeks was a good indication of more night-time sleep at 9 and 12 weeks. Babies who slept well at night were exposed to significantly more light in the early afternoon period. These data suggest that light in the normal domestic setting influences the development of the circadian system.

Night waking, sleep-wake organization, and self-soothing in the first year of life.
J Dev Behav Pediatr 2001 Aug;22(4):226-33

Abstract: Few objective data are available regarding infants' night waking behaviors and the development of self-soothing during the first year of life. This cross-sectional study examined 80 infants in one of four age groups (3, 6, 9, or 12 mo) for four nights by using videosomnography to code nighttime awakenings and parent-child interactions. A large degree of variability was observed in parents' putting the infant to bed awake or asleep and in responding to vocalizations after nighttime awakenings. Most infants woke during the night at all ages observed. Younger infants tended to require parental intervention at night to return to sleep, whereas older infants exhibited a greater proportion of self-soothing after nighttime awakenings. However, even in the 12-month-old group, 50% of infants typically required parental intervention to get back to sleep after waking. Results emphasize the individual and contextual factors that effect the development of self-soothing behavior during the first year of life.

Attachment and sleep: a study of night waking in 12-month-old infants.
Dev Psychobiol 2001 May;38(4):274-85.

Abstract: Sleep regulation was examined from a mother-child relational perspective. Although the link between sleep and attachment has been previously discussed, empirical support is rather limited. This report, which is a part of a longitudinal investigation of sleep in infancy, examines the association between the child's sleep pattern and mother-infant attachment in 94 mother-infant dyads. At 12 months each dyad participated in the Strange Situation procedure; 77% were securely attached. Mothers' description of the infant's fussiness was not found to predict the attachment pattern, but was associated with the sleep habits. It was found that 55% of the secure and 60% of the ambivalent children were described as night wakers. To a sub-group of 37 infants, a sleep monitor (actigraph) was provided for two nights' recordings. The frequency of the objective awakenings was higher than what mothers reported but similar for the secure and insecure infants. The findings confirm that night waking at the end of the first year is a common developmental phenomenon. Among this group of non-risk infants, sleep characteristics were only marginally associated with the quality of the child's attachment relationship.

Sleep: what is normal at six months?
Prof Care Mother Child 1994 Aug-Sep;4(6):166-7.

In this study, part of the Avon Longitudinal Study of Pregnancy and Childhood (ALSPAC), researchers surveyed the parents of 640 babies. Some of the results:

  • Only 16% slept through the night at six months old — 84% were not sleeping through the night at 6 months
  • 17% woke more than once per night, ranging from twice to eight times
  • 5% woke once every night
  • 9% woke most nights
  • 50% woke occasionally
  • 16% of six-month-olds had no regular sleeping pattern
Armstrong KL, Quinn RA & Dadds MR.
The sleep patterns of normal children.
Medical Journal of Australia 1994 Aug 1;161(3):202-6.

The above study is the definitive work on sleeping habits of (Australian) children to 38 months. The researchers surveyed 3269 parents, with a 96.5% response rate, over a one week period. The parents had to report on their child's sleeping habits over the past 24 hours, plus answer a few questions related to their perceptions of their child's sleep behavior.

What did they find?

  • There is a wide range of normal childhood sleep behavior.
  • Circadian rhythm is not well established until four months of age.
  • Daytime sleep becomes less regular with increasing age, the most marked reduction in length occurs around 3 months of age. However, a surprising 11% under 3 months of age don't have a daytime sleep every day.
  • Frequent night waking that disturbs parents is common from 4-12 months (12.7% disturb their parents 3 or more times every night).
  • Night time settling requires more parental input from 18 months.
  • Nearly a third of parents have a significant problem with their child's sleep behavior.
  • Sleeping through the night: 71.4% did this on at least one occasion by 3 months of age, but many of these relapse into more frequent waking in the 4 to 12 month period. It is not until after 24 months that regular night waking (requiring attention) becomes much less common.

Although this study did not address breastfeeding, it is relevant because a lack of understanding of 'normal' sleep patterns can lead to supplementing, early solids, belief there is not enough milk, etc. The authors claim it also leads to misdiagnosis of gastro-esophageal reflux (GER) and overuse of sedative medication. A worrying 31% of 25-38 month-old children were disciplined (mostly smacking) to get them to settle. 27% of parents let their children cry, 11% at less than one month.

A longitudinal study of night waking in the first year.
Child Care Health Dev 1991 Sep-Oct;17(5):295-302.

Abstract: A longitudinal study of the development of sleep patterns addressed the issue of continuity and change in night waking in the course of the first year. Mothers of 118 infants, who took part in a follow-up study of normal babies, completed a sleep questionnaire at 3, 6, 9 and 12 months. Regular night waking was a common characteristic throughout the first year:

% babies waking at night
46%
39%
58%
55%

The number of awakenings per night was a function of age. Following a decline in the number of interruptions from 3 to 6 months, an increase in night waking at age 9 months was recorded. Although the methodology does not lend itself to an objective validation of the changes in sleep-wake states, nor is it suitable for causal explanations, it is, nevertheless, important to note this profile. The increase in night waking towards the end of the first year coincides with significant socio-emotional advances which characterize this developmental stage.

Sleep patterns of New Zealand infants during the first 12 months of life.
J Paediatr Child Health. 1990 Apr;26(2):85-8.,

Abstract: The sleeping patterns of 874 infants aged 1-12 months were recorded by parents over a 6 day period. The most striking feature of the results was the wide range in total hours slept by infants of the same age, for example, the average total sleeping time per 24 h period for 4 month old infants was 14.8 h with a range of 11.0-19.3 h. Furthermore, over the 6 day period, individual infants showed wide variations in their sleeping times with a range as great as 12 h. Despite these wide variations, several clear trends emerged: from 1 to 8 months, a decrease with age of the average number of hours slept per 24 h period; and from 8 to 12 months, and a continuing shift towards a dominance of night over day sleep. The frequency of night wakings was, on average, 77%, a finding that contrasted sharply with parental perception of frequency of night waking; the transition from bassinet/carrycot to cot was most common between 3 and 4 months of age; 25% of babies slept with the light on, 9% used a dummy, and 37% sucked their fingers; first-born infants woke significantly less often at night than those with one or more sibling. These results provide an important comparative data set on the sleep patterns of infants.

Sleep/wake patterns of breast-fed infants in the first 2 years of life.
Pediatrics. 1986 Mar;77(3):322-9.

Abstract: Published norms for infant sleep/wake patterns during the first 2 years of life include an increase in length of maximum sleep bout from four to five to eight to ten hours by 4 months but little decrease in total sleep in 24 hours from 13 to 15 hours. Thirty-two breast-fed infants were followed for 2 years and data collected on 24-hour patterns of nursing and sleep. Infants who were breast-fed into the second year did not develop sleep/wake patterns in conformance with the norms. Instead of having long unbroken night sleep, they continued to sleep in short bouts with frequent wakings. Their total sleep in 24 hours was less than that of weaned infants. This pattern was most pronounced in infants who both nursed and shared a bed with the mother, common practices in many nonwestern cultures. The sleep/wake development accepted as the physiologic norm may be attributable to the early weaning and separated sleeping practiced in western culture. As prolonged breast-feeding becomes more popular in our society, the norms of sleep/wake patterns in infancy will have to be revised.

By default, Windows uses a power plan to save try and save power. It can do this by turning off the display when there is no activity for a given period and also do a similar thing to put the computer to sleep. If you don't move the mouse or touch the keyboard within a specific period of time, Windows thinks you're away and will perform the selected action to conserve power.

However, this is not always the case and sometimes you might not be at the computer but don't want it to shut off the display or go into standby for a while. You can of course go to the Power Options in Control Panel and create or edit a power plan that keeps the computer and display on. Or you can go to Settings in Windows 10 and simply change or disable the sleep timers for the current plan.

If you don't revert the chosen power options back, you're left with settings you might not want on a permanent basis. Some software has the ability to keep the display or computer on while running such as a video player or video encoder but not all software has this option.

A simple solution so you don't have to touch any power plans or sleep settings is to use a third party utility that temporarily prevents the computer or screen from going into standby. Here's a selection of free tools that can help, they were all tested on Windows 10 64-bit.

1. Insomnia

This simple little portable tool will prevent your computer from going into standby while it's running. Insomnia actually tries to disable sleep mode while it's open and then puts the setting back to what it was previously on close. Do note Insomnia has not been designed to and will not prevent your screen from going to sleep.

There are separate 32-bit and 64-bit versions available and you simply run the executable which opens the small window shown above. Although you can minimize the window to the tray, it is meant to stay on the screen as a reminder that your computer cannot currently enter sleep mode.

Download Insomnia

2. Caffeine

Caffeine works in a rather simple way to try and prevent your computer from going into standby, the screen from shutting off, or the screensaver kicking in. This is to simulate a keypress once every 59 seconds so Windows is fooled into thinking you're typing on your computer. The pretend keypress is the virtually unused F15 key although you can change it to Shift or another key if there's a conflict with your applications

A number of options can be edited from the command line or placed in a desktop shortcut. They include the keypress interval (in seconds), use the Shift key or virtually any other key or mouse press, prevent sleep but allow the screensaver, watch for a specific desktop window, and various ways to enable or disable Caffeine. The tray menu has two timers for setting how long Caffeine can be activated or deactivated.

Download Caffeine

3. Insomniate

There are two variants of Insomniate available; the standard version and the simple version. The only difference between them is the standard version has a user interface with a countdown timer where you can prevent sleep for a specific period of time. Both are portable executables.

Insomniate works for the screensaver, putting the screen to sleep, and also putting the computer to sleep. Just run the simple version and let it sit in the tray for it to work all the time. To use the timer, run the standard version, set the countdown, and press the play button. There appears to be no information about how Insomniate prevents sleeping but it does seem to work perfectly fine in Windows 10.

Download Insomniate

4. StayAwake

StayAwake is a relatively old tool from 2012, but it appeared to work just fine in the latest Windows 10 64-bit operating system. It can prevent the screensaver from starting and stop the screen or computer from being put to sleep. StayAwake does this by fooling Windows and telling it the mouse cursor has moved zero pixels.

Simply launch the portable executable and double click the tray icon to enable or disable StayAwake's function. Right click the tray icon and go to Settings to enable a hotkey, display balloon notifications, or use alternative mode. This is a fallback option in case the normal mode doesn't work and moves the cursor a few pixels every second.

Download StayAwake

5. PreventTurnOff

PreventTurnOff is a small but powerful tool that is able to prevent system shutdown, standby, hibernate, log off, and also stop the screensaver or monitor turning off. Every option is very straight forward and if you want to prevent the computer from going to standby for example, just make sure that the Standby checkbox is checked, click the Enabled button and press To-Tray so the program minimizes.

There is also a configurable timer function that you can set when to automatically disable the blocking or force the computer to shut down, log off, or sleep after time expires. The Options menu will allow you to setup a timer to start blocking when the program starts or the system resumes from standby.

Download PreventTurnOff

6. Don't Sleep

Don't Sleep is by the same developer as PreventTurnOff and is essentially a more advanced version of that tool with some extra options. In addition to the features in PreventTurnOff, this program can send the computer to sleep on a mouse/keyboard event and it has more trigger based events that can prevent sleep mode being enabled.

Don't Sleep can also block sleep until the laptop battery is below xx%, disable sleep until CPU usage is below the threshold, and disable sleep until the network load is under a certain threshold. Both PreventTurnOff and Don't Sleep are portable and also have a useful Mini-HTTP feature which can be used to remotely configure the program through a web browser.

Download Don't Sleep

7. Coffee FF

Coffee is a little different from most of the other tools here because it can prevent the computer from going to sleep during certain trigger events. The main trigger is network activity and Coffee can prevent sleep while network speed is above a certain threshold. The other useful function is preventing sleep while a specific program is running. Once the program closes, the sleep timer will be enabled again.

If you want to disable the network trigger and just use the process trigger, set the download/upload speeds to 0, go to the Programs tab, and select a running process from the list. A third option to block sleep mode is to do so for a specific number of minutes, you can set that in the bottom left of the main window. Coffee was created by Steven Cole but subsequently updated by FireFly, hence the FF in the name. Wso2 integration studio download. Portable and installer versions are available (portable is a RAR file).

Download Coffee FF

8. NoSleep

This last utility is incredibly easy to use because it has no user interface or options of any kind. You just run the program and let it do its job. NoSleep fools the computer into believing you are using it by moving the cursor a single pixel to the left and then a single pixel to the right every 30 seconds. This blocks sleep mode for the screen and the computer as well as the screensaver.

There are two versions of NoSleep in the download. The only difference is v2.0 is made using .NET so requires .NET Framework 4.5 or higher. Windows 10, 8 and probably Windows 7 users will have .NET 4.5+ installed. The other older version was made in the AutoIt scripting language and can be tried on machines without .NET although it's reported that this version is less reliable.

Download NoSleep

Final note: As we mentioned at the beginning, most video playing software will prevent the computer from turning off the display or sleeping because obviously it's trying to show video content. An alternative to these tools is to simply load a video into your favorite player, mute the audio, and minimize the window. This doesn't work with the Windows 10 'Movies & TV' player but Windows Media Player does work.

I've used Caffeine for years. Only downside is when run on a multiuser machine. When my girlfriend switches to her user account and then leaves the computer it will go into hiberation, since Caffeine is run from my user which is then 'inactive' due to her active session. Not nearly a catch 22 situation but I would still like a simple method of addressing it.

We'd be giving false info if we said this ran on Windows 10 and it didn't, as we have made no such claim there is no need for a disclaimer.

The post will be updated at some point but it's not a priority.

There is a very easy way to stop your computer going to sleep which bypasses even corporate settings that can't be changed. Just shoot a small video (say 10 sec) on your phone and email it to yourself. Open the video with Windows Media Player and set it to play on a loop. Minimize this window to your task bar and that's it. Your computer will not sleep as long as the video is running.

Awesome way to deal with it. I was also wondering if there was simply a web site that a person would log into to do something similar since a lot of corporate IT don't let the end user install anything. I will give your idea a shot. Thanks for sharing.

I have a windows 7 HP. I left one night and when I came back the next morning I turned it on, and the computer came on, went thru finding signal, then straight to going asleep, and then it shuts down? Can't even get to the first window to fix the sleep mode, what do I do?

There is a legitimate need for something like this. I have Echo Dot connected to by line in to play music via spotify. Laptop connected to receiver /sound system and hdmi to tv. The problem is, an active Line In doesnt prevent the sleep mode from kicking in and, therefore, stopping music. Idealy need a utility to monitor Line In and prevent sleep when active.

I have found 'insomniate' to be the best one so far. It doesnt move the mouse to keep the computer awake. It honestly also has the best looking UI too.

nosleep.exe is one I use often. Moves the mouse cursor one pixel to the left at a regular interval, then one pixel to the right

The reason these program exist, is the fact the corporate networks can use enforced policies on locking timeout, screensavers, etc. that you then cannot change, or revert back to the network default on next boot/login. If you are not in such a situation, you normally never need them, and thus set the power, auto-lock or Screensaver options you like.

Nosleep 1 1 – Prevent Computer Sleep Through The Night Vision

I don't get any of these. They all seem to bypass sleep mode all the time unless you disable them. If that is the case, why not just disable ‘Sleep' mode altogether in the 1st place??

Unless any of these actually recognize when a program is running (a browser downloading files, a defrag tool working or any program that runs for an extended period of time etc.) and then activates. If nothing is running, the program doesn't run letting the system go into sleep mode.

Those which prevent sleep for a specifiable interval of time serve an otherwise unsatisfiable need. I use it when the computer is transcoding a video file, something which may take hours while I am not attending but after which sleep is good.
