How to Use DoNotSleep to Keep Your PC Awake

DoNotSleep Tutorial: Simple Steps to Disable System Sleep

What DoNotSleep does

• Purpose: Temporarily prevents Windows from entering sleep, hibernate, turning off the display, restarting, or logging off without changing global power settings.
• Portable: No installation required; runs from an executable or USB.

Quick step-by-step (GUI)

1. Download Don’t Sleep from the official project page or a trusted mirror (e.g., GitHub / majorgeeks).
2. Unzip and run DontSleep.exe. The app appears in the system tray.
3. Left-click the tray icon to open the main window.
4. Use a preset (10min, 30min, 1h, etc.) or choose “Custom” to set an exact end time.
5. Click Enable (or the corresponding button) to activate protection—DoNotSleep will prevent sleep/hibernate and screen off for the selected period.
6. To stop protection early, open the window and click Disable or right-click the tray icon and choose the off option.
7. Optionally set the program to start with Windows via its settings if you want persistent availability.
