The board does have power sw solder pads near the main power molex but no pins. Bust out the old solder iron and solder your two wires from the arcade button to the back side of that original case tactile switch. Done. --- End quote --- If I do this and leave the old power button in place do you think that the arcade button would function and the computer would not report the error? --- End quote --- Yes, I would imagine so. That motherboard is probably programmed to look for that "daughter-board" every time it initiates. As long as you leave that daughter-board plugged in and solder the wires to the bottom of the power tactile switch, you should be good. --- End quote --- I'll give it a whirl when the buttons get in next week. Thanks for the help! |

OR if you do not want to solder to the board just splice into the proper wires and leave the wires also going to the PCB (rather than cutting the entire thing off like he does in the video.) That way pressing the button will still complete the connection but the connections will still all be in place to avoid the error reporting and the entire thing is still reversable if you decide to change the system later and want your PC back for another use. |

Yeah that's what I was getting at, but he acted like he tried it and it didn't work. I don't see how it couldn't unless the pcb was removed. |

I found this while searching the web that could be super useful. It's a wiring diagram for the harness coming from the motherboard. From the looks of it I should be able to tap the ground (does it matter which one?!) and power (#12) into an arcade button for the fix. it came from a blog at http://mechanicalphilosopher.blogspot.com/2013/07/using-dell-optiplex-745-motherboard-in.html |
| JDFan:
Shouldn't matter which ground you use - to test just get a piece of wire - take the casing off of each end and touch one end to each connection (power and ground) and see if the system starts to boot - if it does you know you have the right 2 spots to splice into. |
