Thanks to this simple feature, you can safely keep your computer on until a specific time and then turn it off to save energy.
This small tool lets you create a countdown timer that, once finished, will disable the program. One of the most interesting features in Don't Sleep is the timer. The same applies if it detects that the screen is about to shut down or the computer is about to go to sleep: it will send a notification to the system and let you know that you still have tasks pending. The way Don't Sleep works is very simple: in short, if it detects that the screen saver is about to be activated, it will make the operating system believe that it has very important tasks to carry out, which will abort the process.
This is particularly useful when you are running older programs in Windows 8, 10 and 11, which sometimes, due to their stricter power-saving measures, can confuse these programs with prolonged periods of inactivity. Don't Sleep is a very simple program that stops your computer from going into sleep, power-saving mode, or performing any other action resulting from inactivity.
