Your system will go to sleep if you don’t use it for a while. This basically means that unless you’re playing a video, simply not tapping a key or moving your mouse for a certain period of time will put your system to sleep. If you prefer that sleep and inactivity are determined by CPU usage, or memory, disk, or network usage, you can use Econap. It’s a free app that can sleep Windows 10 on low CPU, Memory, disk, and network usage, among other things.
Econap will do all of the above for free however, it does have a pro version which enables more features. The pro features let you block sleep if a game controller is connected, if a print job is pending or queued, if you’re using an app in full screen, or giving a presentation.
Sleep system on low CPU, Memory, disk usage
Download and run Econap with admin rights. If you do not run the app with admin rights, you will not be able to customize wake up devices. The other options will still work.
Run the app and go to the Standby Blockers tab. This tab shows you the various items that can be set as the signal for your system to go to sleep. In addition to CPU, RAM, Disk, and Network usage, you will also see blockers for Multiple users, and audio.
You can enable or disable any of the blockers however, your system will only enter sleep, or be prevented from sleeping, if all blockers are within/outside their defined thresholds.
To define the threshold for a blocker, click it and you will see a slider that lets you change the threshold. It also tells you the current state of an item e.g., the CPU usage below is at 17% and you can set the threshold above or below it.
When the app detects that your system’s CPU, Network, Disk, etc., usage has fallen below the set threshold, it will go to sleep. If you’re inactive, but the system’s resources are running above the set threshold, it will not enter sleep.
The app’s blockers are great however, the audio blocker deserves a special mention. Normally, only video apps can prevent your system from going to sleep. If you’re playing a video in VLC player, the Movies & TV app, or in the Netflix UWP app, your system won’t go to sleep but if you’re just playing audio in one of the more popular audio apps, your system will enter sleep which can be prevented with Econap.
The network blocker is also great if you’re downloading something, or have an active process that requires an internet connection. You can use it to prevent your system from going to sleep so long as there is some network activity.
