I use similar code but wondering what the "2" after ScrollLock means/is for? Is that the number of times the key is pressed? because I have been using the milliseconds timer to separate the command twice.
P.S. from what I know, a single $true in while ($true)
will suffice.
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
}
