Amphetamine

Long processes can be interrupted or affected in other ways when the operating system switches to sleep mode or starts the screensaver. If you want to make sure that everything will go without interruptions, you can use Amphetamine to prevent the system from running the screensaver, going to sleep mode, shutting down or restarting. It only takes a few clicks to make these settings, so you don't have to search through any menus each time you wish to disable the screensaver or the sleep mode.

Amphetamine is absolutely free, for both personal and commercial use. It comes in a small setup package, so you can have it up and running in no time. There are no special requirements you have to meet and you won't notice any impact on your computer's performance.

The application has a compact user interface, with three checkboxes and two buttons. All you have to do is choose what you intend to disable, by ticking these checkboxes and clicking a button. The new settings will be applied instantly, and you won't have to worry about the operating system shutting down or going to sleep.

Besides preventing power-related actions, Amphetamine lets you make other settings as well. The application can be set to run at startup, with your power settings already applied. Additionally, you can set the software to ensure that certain services are started. Additionally, the software can send you an email when it prevents a shutdown, and it can also run a program or script of your choice.

With Amphetamine running on your computer, you will never have to worry that your system will go to sleep, restart or shutdown automatically.
