Thread: m2 atx problem

Do you have 12v running to your ACC terminal on the M2?
Come to think of t, an overall idea of how it's wired might be useful, as well.

Do you have a continuity tester? Test the J8 pins for continuity as you apply the power to the accessory wire, and wait about 10 seconds. See if it closes.

Does ANYTHING happen? What MB?

If you push the buton manually? does it turn on? Both from the M2 and the motherboard.

Basically short out the pins in the header on the mobo to turn on, and see if it goes. IF it works try to short out the header for the manual switch on the M2, and see what happens.

This is going to sound stupid and go against most of what you know about on/off headers, but flip the header pin around. Fixes some boards. It did for mine.

Right now if your M2's power wire is black and red, with pin 6 having the black, and pin 8 with the red, switch them, so that pin 6 has the red end of the wire, and pin8 has the black side. Leave it alone on the M2 side.

The M2 works by either sending out a small infantessamle voltage or it grounds a pin. More than likely grounds. But if it is grounding a pin that on your motherboard does not point to ground, you get nada. Just try it.

It isn't always, but it has been known to work. All depends on what your mobo is. I have a M10k too, so I know this works for this type of board. If it works, it just means the manufacturer went the cheap way of building the circuit rather the the full more expensive way. And by more expensive I mean fractions of a penny.
