No, there's a small analog switch on the m4 that acts like a relay and just shorts those two contacts together to simulate the switch.
Anyone having problems with their M4 turning the computer back on after it tells it to shut down?
I've set my PC to shutdown when I turn the car off. No hibernate, no standby. The M4 will shut it down and approximately 1 minute later, it turns it on again. To be sure it doesn't do this, I have to turn the power off to the PC itself.
Anybody experienced this issue? The M4 is a giant hunk O' junk for me. I"m going to go back to my Carnetix regulator and P120 if I can't figure it out. That combination has worked flawlessly for years.
Make sure nothing is shorting your Acc line
The PSU for one of the computers seems to have failed (it's buried in the dash and I have to dig it out) and that may have caused a short.
is there a way to make the m4 switch on the mobo quicker. when it is set to hardoff and the 5 volt rail is gone, it takes 5 sec before the fan starts to spin.
When i use an regular powersupply and unpluged from the 220 volt (us 110 volt) plug it in and directly press the on switch it spins up within a second.
Is there setting in the usb controle sett to speed things up?
