I would like to add a wired momentary start up switch to my old tower computer, then mount the switch under my desk. Answered

I have a desktop Dell Dimension 4300, with a start switch appeared to be nearly inaccessible.  There is a cable ribbon wire leading to the switch. 

I think that I need to add a momentary button.  Maybe someone knows how to access this switch and or the location of the start up pins on the circuit board.  I may be able to wire the new momentary button across those pin locations.  Any help would be appreciated.

Look at the datasheet for your motherboard. It will show you where the header is and which pins need to be shorted to turn it on.

Hello Jayefuu,

Do you know of a link / website where I can look up the motherboard data sheet?

Find the two wires that go to the current switch and splice into them to wire your new momentary switch.
