> Thank you... PostMessage() works to turn off the display, but for some strange reason it can't turn it back on.   I set a 20 second delay, and precisely at 20 seconds my  monitor light turns green, but then the monitor goes back to sleep before the screen can be displayed.  I'm guessing the signal is being sent to turn on the monitor, but not to get windows out of power save mode...  I also  see using -1 to turn the display back on is an un-documented feature.    I can get the display back on with a keystroke or moving the mouse, but I'm wanting the program to turn the display back on without user input.  Can anyone think of any other way I could make my console

I have found this:

It's in c++, but it looks that since w.8, you must simulate a mouse move.
