PC powers off, and then comes back on...
I have my motherboard, and M2-ATX power supply setup on my desk. I have it hooked up using an old ATX power supply. Standard setup to power the M2 and then a switch to simulate ignition wire.
When the power supply is first turned on, motherboard stays off. Turn the ignition switch to "on" and the M2 does what it should. After Windows comes up turn the switch to "off", M2 does what it should. Hibernation, computer off.
Then, from between 10 and 30 seconds, the computer will start to boot back up. I have no idea why it's doing this! I have the restore power option turned off in the BIOS.
Does anyone know what I"m doing wrong??
you have to take the 12V out of the ignition for the psu to stop trying to turn on the computer.
If not that above ^^^, then I would suspect some device is waking up the computer. It could be the mouse, the keyboard, or the network, maybe even the touch screen? You could check on the control panel, double click on a device, then go to the tab "advanced power options" and uncheck "allow this device to wake the computer". Or you could unplug everything and see what happens.
Isn't that what the switch is for? Ignition connected to one side of the switch and 12v connected to the other? On = M2 thinks ignition is on, Off = M2 thinks ignition is off?
Anyway, I think I figured it out before you replied RipplingHurst, but I believe you are right. I think the LAN connection was waking it up...that's really weird!
I'm going to check device settings...I thought you had to explicitly tell it to do that...I didn't think it was the default :P
You never told us what OS you're using, but the default for Windows 7 is to wake on LAN. Don't remember having that problem with XP, but as soon as I upgraded to Windows 7, same machine, that started to happen.
Yeah, this is Windows 7 :P Good job on that M35 btw, that's pretty slick. I used to have a G35 6MT. Traded it in because the clutch in those things is horrible! Also gas mileage was an issue
I think that I want to do something with some switches...I'd really like to bypass the ACC line in certain situations. Like running errands, constantly getting in and out of the car...don't want the computer turning on and turning off over and over if it won't be in use.
Would you basically just wire the switch inbetween the ACC line and the carpc? That way if the switch is off, the M2 never sees it, and if the switch is on, it's basically just as if the switch was not there...right?
As for the M35, Thanks! I miss the M, it was a great car.
Yes, you can do that with a switch on the ACC line, most do, so when you go for service/valet parking, you can keep the computer off even if the car is on. A SPST you can buy at Radio Shack will do.
