Hello!

I have used the following code to turn off my monitor:
Code:
#o:: 
    Sleep 01000
    SendMessage, 0x112, 0xF170, 1,, Program Manager 
return


I also want to add functionality that keeps the monitor off unless space bar or some other key is pressed, BUT all other keys keep operating normally.
The reason I want to do this, is that I can continue to control Winamp even when the monitor is off.
Help is appreciated!

How about changing the Display Properties so that the output is not going to the laptop's LCD? For example, switch to the VGA port (where there presumably is no monitor). I think that would achieve the desired effect.

jaco0646 thanks for your reply.
If I am getting you correctly, you mean creating a script which actually does the same as fn+F5?
Help will be appreciated in creating the script Laughing

Some trial and error and actually I did do it! Very Happy
A simple loop with the getkeystate solved my problem.
Any way, thanks for your help

After further investigating the script I wrote, I saw it wasn't a good script.
Meaning, while the script was in the loop, the CPU usage climbed to 50%.
The logic of the script was to keep sending the command to shutdown the monitor till one of the keys (space, left mouse button, right mouse button) were pressed:
Code:
^esc::   ; ctrl+esc hotkey that turns off the monitor.
    Sleep 1000   ; Give user a chance to release keys (in case their release would wake up the monitor again).
     Loop
     {
         ; Turn Monitor Off:
         SendMessage, 0x112, 0xF170, 1,, Program Manager   ; 0x112 is WM_SYSCOMMAND, 0xF170 is SC_MONITORPOWER.      
         ; Note for the above: Use -1 in place of 2 to turn the monitor on.
         ; Use 1 in place of 2 to activate the monitor's low-power mode 
         If ((GetKeyState("Space","P")) Or (GetKeyState("LButton","P")) Or (GetKeyState("Rbutton","P")))
           { 
               SendMessage, 0x112, 0xF170, -1,, Program Manager
               break
           }
      }
return

If anyone knows a way to boost this script into a better one, I would appreciate it.
Thanks,

         ; Turn Monitor Off:
         Sleep 1000
         If A_TimeIdlePhyiscal < 2500
         {
           SendMessage, 0x112, 0xF170, 1,, Program Manager   ; 0x112 is WM_SYSCOMMAND, 0xF170 is SC_MONITORPOWER.     
           ; Note for the above: Use -1 in place of 2 to turn the monitor on.

               break
           }
         }
      }
return

That should cut down on CPU load and only turn off the monitor a few seconds after the user has done some input.
