ATX turning on at boot with setting disabled #14

Open terabyte12 opened 4 days ago

terabyte12 commented 4 days ago

I have both the "Turn on ATX on Boot" and "Follow USB Power" settings disabled yet when power is first attached, and the controller boots the ATX Supply is turned on.

Controller version 1.2.0

Power Toggle via the Board Button, Case Power Switch, and Web Management works as expected.

Thanks for the report, I've been looking into reproducing this behaviour but haven't been able to. Code-wise there's only four places where the power supply can be turned on:

With both the on-boot and follow options turned off, that'd suggest to me the power button is the most likely trigger. Is the power button maybe being shorted? Or are the power switch pins tied together otherwise?

I checked and I do not think the power sw is being shorted. The switch works perfectly to turn on/off after the boot up. I'm using the official SuperMicro Chassis front panel ribbon to break out cable. I did notice that simply plugging/un-plugging the PS SW header triggers on/off. I also am not able to get any of the front panel leds to illuminate with the PS LED header. I briefly got one led to light (the Over Heat LED) using the header but no longer. Perhaps my chassis Front Panel is suspect.

I'll try probing with a meter tomorrow.

I have the same behavior in my Supermicro 826 case with the LEDs not working and removing the switch header causing a power off.
