A free app for Windows, by Nenad Hrg.

Don’t Sleep is a small Freeware Windows program to prevent system shutdown, Standby, Hibernate, Turn Off, and Restart.

It is specially designed to prevent the deactivation of the computer, the inactivation of the monitor or the activation of the screen saver.

This is a practical function that prevents the PC from running unnecessarily since not every PC is equipped with a quality power supply that consumes 1 Watt in standby mode.

Don’t Sleep can also serve as a general protection if you have started a background service or application and want to prevent turn off of the computer by itself, or other persons ergo accounts.
