By default Windows uses a power plan to save energy. It can do this by auto 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 and touch the keyboard within this period, Windows thinks you’re away and will perform the selected action in an attempt to save some 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 little while.

You can of course go to the Power Options applet in Control Panel and either create or edit a power plan that never goes into standby mode or turns off the display. The problem is if you forget to set it back to your chosen power plan, Windows obviously won’t set these options back by itself and you’re left power settings you might not want on a permanent basis. Luckily some software has an option to do this while it’s running such as a video player disabling the monitor shut off function when a movie is showing.

Available on the Mac App Store here for 99p, this app overrides the Energy Saver settings to keep your Mac awake, preventing your Mac from going to sleep. Apr 07, 2020  caffeinate -s Keep the Mac awake while it is plugged into AC power. Caffeinate Now, your Mac will stay awake for as long as you leave the Terminal running. To stop this, use the keyboard shortcut Ctrl+C. Caffeinate -t 1800 & Here 1800 is the time in seconds. You can set it to anything. Now your Mac will stay awake for this time duration.

Not all software has this option so to solve the problem, simply use a third party utility to temporarily prevent the computer from going into standby. Here’s a selection of small tools that can help.

1. Insomnia

This simple little tool will simply 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. It has not been designed to and will not prevent your screen shutting off.

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

2. Caffeine

Caffeine works in a rather simple way to try and prevent your computer going into standby, the screen from shutting off or even the screensaver kicking in. This is to simulate a key press once every 59 seconds so Windows is fooled into thinking you’re using your computer when in fact, you aren’t.

The key it pretends to press is the F15 key which is virtually never used on any keyboards, although you can change this to Shift and the number of seconds can be edited from the command line if you want. Caffeine is a tiny 13K executable and it places an icon in your tray which you double or right click to enable or disable it.

Caffeinated is a clone of a similar Mac OSX tool called Caffeine and stops your computer going into standby. The program uses a Windows function called SetThreadExecutionState which software applications use to tell the operating system they are in use and prevents the computer sleeping.

Although it’s a portable tool, there is an option to start with Windows and also a default duration to keep the computer awake can be configured of 5 minutes to 5 hours or indefinitely. The .NET Framework 3.5 is required and the author says he has only tested Caffeinated on Windows 7.

4. Noise

Noise is a very basic tool that simply sends a keystroke to the system every 60 seconds so Windows believes someone is actually pressing a key on the keyboard and therefore doesn’t run the screensaver or enter sleep mode.

Run the tool and double click on the tray icon to open the tiny dialog box, then enter a key which the program will send once a minute. Letters and numbers in combination with the Shift key can be used, not Ctrl or Alt etc.

5. Don’t Sleep

Don’t Sleep is a small, simple and yet powerful tool and is able to prevent a system shutdown, standby, hibernate, log off and also stop the screensaver or monitor turning off. Every option on Don’t Sleep is very straight forward and if you want to prevent the computer from going to standby for example, just make sure that the Standby check box is checked and click the Enabled button.

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

A useful addition is the Mini-HTTP feature which can be used to remotely configure Don’t Sleep through a web browser. You can enable it by clicking the Don’t Sleep menu bar and select “Enabling the Mini-HTTP feature”. Once enabled, you can access the settings by typing http://IP.Address:8080/ in any web browser. It is also possible to use the login feature to prevent unauthorized users from accessing the Don’t Sleep settings.

Don’t Sleep is a very useful tool which does the job and takes very very little resources and is less than a 100K executable. It’s free, portable and works on all Windows including both 32 and 64 bit.

On my Windows 10 Pro, Don’t Sleep didn’t work anymore. Neither did Insomnia. But Caffeinated does the trick. OTOH, on caffeinated’s web site, someone commented in 2017 that it didn’t work on his Windows 10 Pro. So…

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.

Im trying to find something to give periodic movement to mouse.

Hi,

Why don’t you update this post? Insomnia doesn’t work with Windows 10. You’re basically giving people false info if you don’t include this disclaimer. I’m using the same version as in your screen shot.

Reply

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?

Reply

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.

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.

The problem as usual is M$’s stupidity& stubbornness. Poor design, poor thinking with nothing being done to fix anything, just add new crap no one wants.

I agree !!!

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.

Because with the last windows update, my work PC now goes to sleep if i use the ‘lock’ function, even with sleep=never selected. Very frustrating when it takes my PC 10 minutes to ‘warm up’ and function correctly.

I stay you must add StayAwake bu only works on windows 7. I tested it on my windows 10 but there is an error. On windows 8 I haven’t tested it yet.
