Caffeine is a program that will allow us to keep our computer awake. How? Very easy, simulating that a key is pressed every 59 seconds. In this way, even if our computer has a problem with sleep mode or the screen saver, we can prevent it from going to any of these states.
Using Caffeine is very simple. We will see the icon of the coffee maker in our task bar and we will only have to double click on it to activate or deactivate it. When the coffee maker is full, the program is activated. When the coffeemaker is empty, it is disabled. As simple as that.
Caffeine is a program that can be especially interesting for users who have problems with Windows sleep mode, since thanks to it the computer will never crash or go to sleep automatically.
