Actually, there were some few thousand boards that would not boot 1/2 the time the power LED was connected. It turns out the printed documentation was in error and was telling the user to connect the LED to the RESET.
When I first bought my motherboard it would not run. The power came on but it was dead other wise. However the hard drive led would light but the power led would not unless I got a beep out of the system. Then it would light so dimly that you had to peer right into it to even see it. I ended up sending that board back, and they said it was bad and sent me a new one. Ok, I've finally gotten around to messing with the leds again because this new board even though it runs has the same problem with the power led. If I turn the connections around I get absolutely nothing from it.
I was under the impression that connecting the wires backwards or a bad led either one would result in no light at all. Has anyone heard of a problem like this?
