Caffeine++ is a free, open-source console application written in C++ that can prevent the system from entering the power-saving mode. Basically, it prevents the screen from turning off and your computer from going to sleep. This application was developed as a command-line alternative to Linux caffeine on Windows.

Caffeine++ supports command-line arguments with the following options:

arguments:
  -m,       -start-minimised       start with the window minimized
  -t time,  -timer                 runs for a specific time in seconds
  -i,       -hide-console          hide cmd
  -k,       -simulate-keypress     Simulate key process in the console

• Hide console can be used if you want to "start the program as a service" by placing a shortcut in the startup folder in Windows.
• Simulate keypress is an option used simply as graphic animation and nothing more

> caffeine++.exe -t 3600

> caffeine++.exe -t 3600 -i

> caffeine++.exe -k

The command line arguments can be used in the command prompt but also as parameters in the shortcut.

• create a shortcut pointing to the executable file
• open the shortcut’s Properties window
• in the shortcut tab, add your parameters to the target field
