Gah! You're right! Bad grammar usually bugs me too.

Since my p1900 does not shut down mine with the short press it sends to the button it eventually just kills the power after about 45 seconds. I have not experinced anything bad from this yet, but would really like for someone to write some code that will detect the power buttom press and shut this thing down proper. If I shut it down manually then when I turn off the key it will send a button press signal( thinking it is shutting it down) which will actually be starting it again. And then it will kill the power in 45 seconds during the restart. I've opted to just close my running programs and then let it kill the power for now.

I've been doing a little bit of research on this. I don't have an answer but I do have some info.

First, the Mac uses Open Firmware to, among other things, control the behavior of power settings.

Second, the Open Firmware command "pmset" is used to control power settings. Here is a link to the man page for pmset: pmset

I read through it and I'm still unclear whether the "pmset powerbutton" entry will change the behavior of the mac to sleep on power button. I think it may simply duplicate what you can already set in the power settings control panel (either sleep or don't).

I've also found out that you can enter "sudo /sbin/shutdown -h now" on the terminal command line to shut the machine down. It would be easy enough to tie an Applescript to this entry but the trick would be to trigger the script. The code is:

tell application "Terminal"
do script "/Path/to/ShutdownScript.sh"
end tell

Where "ShutdownScript.sh" is a Unix shell script that has the command in it.

More simply, ou can also use the Applescript command: tell application "Finder" to shut down

What I haven't been able to do is figure out how to get notification that the power button has been pressed. There's sure to be a way to know this, but I haven't yet found it.

Any way to remap the sleep command so it actually shuts down? Just another approach

I've found an SDK on the Apple developer's site that gives info on how to register for power events, including being informed when the sleep button is pressed. Still not sure I understand everything but this definately looks possible. I think I'll post the question on the Applescript developer's list and at least ask about where to find out the answer to this question.

Good idea... I was actually going to ask a friend or two of mine who are apple developers. Ill let you know if I find out anything helpful.

While your'e at it, could you start a thread here, or could someone else who can better articulate on the subject than I? With a good title we might find the answer from one of the bright individuals here on mp3car!
