iMac 5,1 (late 2006) - Wiring an additional power button

by dereism / May 13, 2013 12:07 PM PDT


I am attempting to add an additional 'power' button (or reset button) to an iMac Core 2 Duo.

I tried soldering a single lead from each of the two connections found beneath the left speaker which were wired to a breadboard with a 6mm button. This seemed to do nothing. The stock button worked as expected, but the secondary button was without function. I did some simple fiddling, but I could not seem to figure out how to get a secondary button to operate.

Is there a kind soul out there who might have insight as to how to best wire a secondary power/reset button for an iMac 5,1? I would sincerely appreciate it Happy

(NT) How do you know the new button is good?

A good question...

That is not a bad question. I didn't actually test a few buttons, now that you mention it. The button I used was from a new stash, though it certainly could have been a dud (as can be the case with these cheap components).

Does that simple wiring idea make sense, though? It seems alright to me, though I can't be certain that there isn't some logic or some such nonsense implemented in that round chip between the button and the board.

It would be fantastic if it was just a bad button, though I fear it is more complicated. I'll try known-good button this evening.

Thank you for the reply.

(NT) Seems fine. But an Ohm meter would be best.
