trying to wire an arcade button to the power button on my pc

<< < (2/18) > >>

I think that daughterboard on the frontpanel attaches to the main panel via a multipin connector sort of like the FP of most motherboard connections except it is probably not documented by Dell and the connector is one piece not separate bits like most front panels.   If you can take the connector off the MB then you can use a multimeter to determine which contacts are closed when the power button is pressed.   You do not have to get the frontpanel off.

Ok I have a multimeter and I know of the multi pin connector you are speaking of.  I had it disconnected last night in my efforts to get to the front panel.  It is a ribbon coming from the front panel power button and it plugs into the I/o board which is connected to the system board.  So if I unplug the power ribbon from the I/o, I'm to prod my multimeter into the female connector on this I/o board correct?  Nit the unplugged connector leading to the power button... Or do I have it backwards?  Also, which multimeter prods am I sticking into the holes?  Can I achieve the correct reading with the pc power off or should it be on?  What should I be looking for the multimeter to display?  Sorry, I bought the multimeter when I started collecting real arcade games to test voltage, never used one in this scenario.

OP when copying and pasting your post from other forums, At least make it easier for us to help you by double checking your post for broken links. The page it can be had now. Hopefully.... I accessed the page five minutes ago, but now the DELL site is acting like it's not there anymore. WTF?

The iopanel (If the link is working today) board appears to be a little more involved than that. His best bet is probably the ribbon cable on the right (if the page ever loads for anyone, might be a good idea to zip it and post it here) which appears to attach to the front panel itself rather than the ribbon cable (Is that an IDE cable?!) that connects the daughter board to the motherboard.

If there's IC's on the board then something is getting modified between it and the motherboard.

Sorry about the broken link.  So in order to trace the switch leads I'm goin to have to remove the case's front panel, correct?

No, I thought about it some and modified my original post. You might be able to do it by checking the ribbon cable that runs from the iopanel to the front panel. I think it's a ribbon cable. Kind of hard to tell if I can't double check when DELL keeps taking it down.
