$timerseconds = 60 * 4 ## Every 4 minutes

$myshell = New-Object -com "Wscript.Shell"

while ($True -eq $True) {
    $myshell.sendkeys("{SCROLLLOCK 2}")
    Write-Output "Keeping Awake... $(Get-Date)"
    Start-Sleep -Seconds $timerseconds
}

Yup, the 2 is to "press" the Scroll Lock key twice. This will toggle it so that it triggers the computer to stay awake while basically keeping the state of the Scoll Lock key the same. So you don't have the Scoll Lock turning on and off every few minutes. It worked well for my usage.

simpler in a profile function, sleeps for 4 mins and scrollLock on/off
cat function:myAlive

$WShell = New-Object -com "Wscript.Shell"
while ($true) {
$WShell.sendkeys("{SCROLLLOCK}")
Start-Sleep -Milliseconds 100
$WShell.sendkeys("{SCROLLLOCK}")
Start-Sleep -Seconds 240
}

I present to you the ultimate oneliner, StealthCoffee:

• Creates a hidden window to run the new process
• Autoexits the original window we paste this into
• Stops running at 18:15 +/- 5 localtime of the same day
• Sends scroll lock twice (random ms range 103-153) in random intervals between 33 seconds and 183 seconds

Repo to open in incognito and copy the oneliner from: StealthCoffee

Here is the snippet also, you can just copy paste it in a Powershell terminal:

---

Start-Process powershell -WindowStyle Hidden -ArgumentList '-Command "$wshell = New-Object -ComObject wscript.shell; $end = (Get-Date).Date.AddHours(18).AddMinutes(15).AddMinutes((Get-Random -Minimum -5 -Maximum 5)); while((Get-Date) -lt $end){$wshell.SendKeys(''{SCROLLLOCK}'' ); Start-Sleep -Milliseconds (Get-Random -Minimum 103 -Maximum 153); $wshell.SendKeys(''{SCROLLLOCK}''); Start-Sleep -Seconds (Get-Random -Minimum 33 -Maximum 183)}"'; exit

---

ProTip: Don't save it as a file locally. I don't have this script anywhere on my local machine to avoid any detection, i just open an incognito window in Google Chrome, navigate to the public repository i listed above and just copy paste the raw text from the file in a Powershell terminal.
