My 2nd post had some pics. If you look at the 3rd pic, you'll see the while wiring assembly
On the left hand of that picture is the buttion/LED part. The bottom 1/2 of that is the button. Top is LED's. There's a total of 8 wires. 4 go into the button, 2 each for the 2 LEDs.
The harness on the right of that picture shows the 8 wires (it's blurry though)
It is a weird setup as I was expecting 2 wires just for the button.

Sorry, I totally missed the pics (and apparently all the usefull words in every one of your posts.) :dunno I thought you said 4 wires from the MB not 4 from the switch itself, I was totally confused. I am beginning to wonder if I blacked out half way through this thread and decided to post anyway :dizzy:.
If you just momentarily contact the first pair, (no shutdown, just power down) does it function, or do you need to hold them together?
And the other pair that does Windows shutdown, I assume it works with a momentary contact of the two wires.
The reason I ask is that it seems more likely that the time-sensitive aspect of the circuit is on the MB than in the switch. If that was the case then you could just use a DPST momentary switch (DPST=switches two independent circuits at the same time) with one circuit being the instant off pair and the other being the Windows shut down pair. If you hold the switch it would power down and if you tap the switch it would shutdown.

OK here's what I did. Had a wire with a momentary switch on it.
Placed that on the 1st 2 pins. Fired up Windows XP.
Pressed button. PC Powers off--no shutdown no nothing just clean power off.
Moved wire to 2nd set:
Pressed button: Windows performs shutdown/standby/whatever it's set up to do on button press--but I have it at shutdown.
Pressing button on both sets while powered off will power up.
Now, when I had this PC at my office, I've had some instances where XP would HANG UP. Just pressing the power button (on the front) for several seconds would power off the PC.
It is weird. But right now, I have something on the 2nd set of pins and this will do what I want!
Now if I can figure out how to get one of the molex connectors from the power supply OUTSIDE the box, I'll be a happy camper!
kelroy:
if you want the computer to power on when the main power for the machine is on you need the following parts:
12VDC/1A SPDT Micro Relay
Model: 275-241 | Catalog #: 275-241
Compact 5VDC/1A SPST Reed Relay
Model: 275-232 | Catalog #: 275-232
standard molex hd power connector
5v dc walwart
connect one reed to the main power connect one to the computer power supply have the output of the one connected to the computer power supply breaking the output to the one connected to the main power. have the ouput from the main power going to the computer powerswitch. i will find some way to make a schematic it is pretty simple.
