Caffeine v1.64

billon on 26 Sep 2017

Caffeine prevents an automatic screensaver or going into standby/sleep/hibernate, useful for presentations or playing video. It works by simulating a keypress once every 59 seconds, so your PC thinks you're still working at the keyboard. Double-clicking the program icon "empties" the coffee pot and temporarily disables the program, while doing this a second time re-enables it.

Other command-line arguments for more functions are present on the web site.

Category:
System Requirements: WinXP / Vista / Win7 / Win8 / Win10

@Napiophelios: Likely won't work for WoW or any other network game produced after about 1999, because they look for game activity (positions and actions and other more clever things) for determining idle players, which has nothing to do with your computer sleeping or screensaving. Pressing F15 (which is what I assume this program does once per 59 seconds) has nothing to do with gameplay so it won't reset any idle timer on the server side.

v1.6

I wonder if this would work with World of Warcraft to keep me logged in while I sleep? :)
