What is PreventSleep?

PreventSleep is a convenient tray utility designed to keep your PC awake by preventing it from automatically entering sleep mode, dimming the screen, or activating the screen-saver.

You can easily enable or disable PreventSleep by double-clicking the tray icon located near the clock on your taskbar.

When PreventSleep is activated, an icon featuring three Zs with a slash will appear, indicating that sleep mode is prevented. Conversely, if the utility is disabled, the icon will simply display three Zs, signaling that your system is allowed to sleep.

PreventSleep is particularly beneficial for users who require their systems to remain online continuously.
