Front panel power button issue

I recently put a new Asus mobo into an HP pavilion case. Everything works, except the power button. Since it was a different layout, I used two 2-pin extenders for the power and PLED (there is no reset button). But the power button doesn't work. Yet the computer will turn on and off if I unplug, and plug back in the extender. I can't get to the wiring on the button itself because of the way the case is pop-riveted together. Also, the light isn't coming on. I double checked to make sure the right connectors are in the right spot. Any ideas? Hopefully I'm just doing something stupid.
