I have a system with an external device that should be able under circumstances to 'wake up' windows if it's in standby mode. I found a lot of answer/response to put the operating system in standby but nothing to force it to wake up.

Is there any way to do this in C# ?

    Don't know if this maybe applies to you, but there's "Wake on LAN" ... – Fildor Jul 01 '21 at 12:17
  • ^^ That is: you can configure Windows, so that when it receives a special "magic packet" on LAN, it wakes up the system. That would of course mean, that your devices have LAN connection. And you need to provide a means to configure Windows for that feature and your device to target the machine it is connected to. – Fildor Jul 01 '21 at 12:27
