Title: Extending CPU power switch (Dell connector)
Post by: Dougmeister on March 26, 2005, 03:05:46 pm
Have the stupid proprietary connector running from the power on/reset buttons on my Dell to the motherboard.  8 dif't sets of jumpers on the MB, none of them really marked.

1) Will I hurt anything by randomly shorting out two pins at a time to see which ones are the power?

2) It is a Dimension 4100, P3-733, if that helps.  Around 5 years old.

3) Is there a recommended way to splice the wires?  Or should I try to solder onto the little circuit board w/ the switches?

4) Is there an easier/better way?

Thanks.  I've read up on this a good bit and most people seem to recommend those splicing connectors.

1.) Probably not. I've done it many times and never had anything blow.

2.) Not really.

3.) Just unplug the power switch connector from the mobo, get a spare plug thingy for it and wire that to whatever you want the new switch to be.

4.) Yes, see 3.

Butt connectors will work good.  If you don't have any, twist the ends of the wires together and wrap with electrical tape.  I would actually trust a connection like this more than the butt connectors.

Thanks for the ideas.

The actualy connector has room for 16 pins, but one is solid, so only 15 pins on the motherboard and 15 openings in the "molex-like" connector.  It uses a ribbon cable in-between the connector and the circuit board that has the momentary on/off buttons.

By looking at the back of the circuit board, each button has four (4) traces that lead to the wires.

Am I better off finding  a "spare plug thingy", splicing into the ribbon cable, cramming some wires into the existing 15-pin connector on the motherboard, etc.?
