Suspend your workstation after Idle-Timeout with PowerShell
#
# This background job automatically suspends your Workstation after a specified amount of
# time. It will come in handy if Windows sleep feature seems to go AWOL.
#
# start with
# powershell.exe -windowstyle hidden -executionpolicy Unrestricted P:\ATH\TO\logoff.ps1
#
# `-windowstyle hidden` will make your PowerShell disappear/run in background
# `-executionpolicy Unrestricted` will enable this PowerShell process to allow non-signed scripts
#
# This is the only setting: How long before suspending?
# Alternative Options:
# * -Seconds 10 ( = 10 Seconds)
# * -Minutes 10 ( = 10 Minutes)
# * -Hours 10 ( = 10 Hours)
#
$idle_timeout = New-TimeSpan -Minutes 45
# DO NOT CHANGE ANYTHING BELOW THIS LINE
