Helps prevent your PC from locking or shutting down.
Caffeine is a free and portable tool which can prevent your PC from going into sleep mode.
As a portable program, it doesn't require installation which means you can run it from anywhere including removable storage media. No installation required.
The way the application works is by simulating a keystroke every minute or so, thus preventing your system from entering into hibernate, sleep or even running a screensaver.
Accessing Caffeine is easy, as it permanently resides in the system tray and an indication if it's active or not is when the cup of coffee is full or empty. In terms of system resources, Caffeine is light and not noticeable.
All in all, it's a useful application for those who'd like their PC to stay awake, overriding any specific power plan schemes or manufacturer-installed power management applications.
