Albeit fulfilling a seemingly simple purpose, Don’t Sleep proves to be handy for some users. This free-to-use utility is designed to prevent your computer from entering sleep mode, activating power-saving measures, shutting down automatically, or taking any other action triggered by periods of inactivity.

Keep your screen awake

Don’t Sleep operates on a straightforward principle — if it senses the screen saver is about to activate or the computer is preparing to sleep, it effectively convinces the operating system that there are important tasks in progress, thus aborting the sleep process. This is especially useful when running older software on modern operating systems.

Beyond its primary function, the app also has a timer that allows time-controlled blocking or shutting down of your computer. Such a feature comes in handy during long downloads or software installations. However, using an app like this can drain the battery quicker than usual.

Reliable but can drain the battery quickly

Overall, Don't Sleep is an invaluable tool that ensures your computer remains active and prevents automatic shutdown, especially during critical tasks. It comes with a timer, a function that enhances its usability during prolonged downloads or software installations. However, keep in mind that the frequent usage of this tool can drain the battery.
