There are many times you need to leave your computer while you are working on some thing and you need to go away from computer or laptop for some time, in that cases its better that you save some energy by turning off the monitor to save some power and save some battery if you are using a laptop this way to get more backup time.
Sleeper is a single executable, a portable (no need to install) application, that will occupy no or very less memory in your system, since it will just give a “sleep” command and then it will close immediately. In my case I created a desktop shortcut and pinned it to my taskbar for quick and easy access as shown in the image below.
You can place it in a folder of your choice and create a shortcut to it in the Start Menu and then right click on that shortcut to define whatever hot-key you prefer to run Sleeper and activate the power-save mode of your monitor. Quickly get your monitor to sleep with a simple hotkey using Sleeper.
You might be thinking about the power saving mode in windows, Of course, you can tell Windows to activate power-save mode after a time of inactivity, but a keyboard shortcut is the most flexible solution, letting you rely on your decision, instead of some automatic adjustment which sometimes ’strikes’ exactly a few seconds before you need your monitor again.
I know there is also the obvious On-Off button of the monitor itself, minimizing even more power consumption and monitor decay, but next to that, a keyboard shortcut to enter power save mode is the best way.
