No Sleep

Keep your computer awake by programmatically pressing the Scroll Lock key every X seconds.

Features⚓︎

  • Runs in Windows system tray with a context menu
  • Start / Stop / Exit options directly from tray icon
  • Displays elapsed time on left-click balloon tip
  • Minimal CPU and memory usage
  • Powershell .ps1 script, no external dependencies
  • Automatically toggles Scroll Lock key every X seconds to prevent sleep

Installation⚓︎

  1. Save the script1 as NoSleep.ps1.
  2. Ensure PowerShell execution policy allows running scripts:
Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned
  1. Double-click NoSleep.ps1 or run from PowerShell:
powershell -ExecutionPolicy Bypass -File "C:\Path\To\NoSleep.ps1"

Usage⚓︎

  • The tray icon appears after the script runs.
  • Right-click the tray icon to access context menu: Start / Stop / Exit.
  • Left-click to show balloon tip with elapsed time.
  • The script will automatically toggle Scroll Lock every 2 minutes (default).
  • Stop or exit from the context menu to terminate the script safely.

How It Works⚓︎

  • Uses .NET Windows Forms for system tray and icon.
  • Uses WScript.Shell to send {SCROLLLOCK} key presses.
  • Runs a background job to periodically toggle Scroll Lock.
  • Handles Start / Stop / Exit actions through tray menu events.
  • Uses a Stopwatch to track elapsed time for balloon tip notifications.
  • Attempts to hide PowerShell console to run silently in the background.

Notes⚓︎

  • Make sure Scroll Lock key is not used by other applications while running.
  • Script uses [System.GC]::Collect() for minimal memory footprint.
  • Tested on Windows 10 and 11.
