Your Mac or Windows computer automatically goes to sleep or locks itself to save power and prevent other users from accessing your device. While this is useful, it can quickly become a nuisance if you have important tasks to complete and cannot waste time to wake up your device when it is left idle for a few minutes. You can change this default setting by changing the Energy Saver settings on Mac and turning off Sleep settings on Windows.
There are also a few tools that you can run to keep your device from sleeping. Below you’ll find some of the popular ones for Mac and Windows.

The app works by moving the mouse right and left every thirty seconds, so your PC doesn’t go to sleep or get locked when it is left idle. There are no configuration options, and you only need to start it. Your PC will remain active as long as the app is running.
However, the app isn’t installed on your computer, and hence, you need to start the app when you want to use it manually.
