Last....... i spend 2 hours search this info on my mobo with multimeter and testing.
I'm not sure if this belongs here but I'm using this computer without the case so I had to find out where the power switch was located on the mobo. After a bit of searching, I found a site with some of the pinouts listed.
I just finished figuring out how to do this, and I rang out a bunch more of the wiring than was previously posted.
here's a diagram of the connector on the motherboard:
33 31 29 27 25 23 21 19 17 15 13 11 9 7 5 3 1

34 32 30 28 26 24 22 20 18 16 14 12 10 8 6 4 2
The 34-pin ribbon cable runs to a small sub-board for the front panel, which includes a 16-pin(2x8) header which gets another ribbon cable that goes to the "sub-sub-baord" for the actual poanel light and switches.
The table below shows the functions of the pins on the 34-pin connector, plus where they connect to on the 16-pin "sub-board" header.
34-Pin function 16-Pin
1 GND 3, 7, 15, 16
10 ? 11
20 Pwr Switch 2
22 HD LED 4
23 PWR LED - 5
24 ? 13
27 PWR LED + 9
28 ? 8
I hope this saves somebody an houtr or 2.
It took me about that long to find it. I need to buy a multimeter.

Why not solder to where the switch goes into the MB?
Just my input, I just built a carpc with the dell GX270 with the new M4-ATX 250 watt 12volt psu, hooked up to the front control inputs on the sub board using the info above all works great. Thanks for your great info.
All the best
Thank you for doing the work! I bought a case with a coa only and can now use that case to build a good pc.
I need to figure out how to mount a motherboard on the odd looking motherboard mounts.
.......sorry, but I love Windows XP Home Edition and Bill.......
