I am trying to cnfm the MB details, so that I can work out the connections for the MB from the box.

I have what I think is a HP EVO4000 MB, A/S no.253242-002 S/P no. 277498-001.

I am trying to work out the connections on the motherboard for the on/off switch; power led; hard drive led; re-set button etc. they are a bunch of individual connections fro the box.
I can identify the group of pins on the MB but they do not seem to indicate what connects where.

Can anyone help?

If what you're trying to do is confirm what motherboard you have, then I suggest this free utility that you can download called Everest.

Download here:

Its a systems diag. tool that identifies most everything hardware related on your system, and then some.

That is partly what I am trying to do, I think I am right in saying that it is an HP EVO4000 etc.

What I cannot find out is the connections on the motherboard for the on/off switch, hdd led etc.

How do i work out which is which?

Your mobo will have the manufacturers name and model number written on it somewhere.

Once you know what that is you can go to the manufacturers website and download the user manual for your mobo.

I have tried that and get a nice diagram but nothing that tells me what each of the connection pins to the front panel is.

See the att link gives a nice pic but does not tell me the pin connections.

You may just have to dive in and start shorting adjacent pins. The system will power up once you hit those, so put your power button leads on there. Once you have the system on, take a multimeter, ground one probe and start poking the pins again. When you find one with 3.3v on it steady, thats your power on LED and one of the adjacent pins is a ground. Poke some more while the system is starting up and the pin with a pulsating or intermittent 3.3v is the HDD light. Finally start shorting the adjacent pins left over until the computer resets, and you've found your reset leads.

Or it sounds like a good plan anyway :D
