My M2ATX sometimes turn of my computer and sometimes don't. Will your chip solve this problem?
It depends on what is causing your computer to not turn off. What happens when your computer does not turn off? Does it start to shut down and not have time to finish or does it just sit there as if the ignition had never gone off?

Exactly, my computer still runs as if the ignition had never turned off. When I purchase M2 - ATX, turning on/off has worked perfectly. It stops working after one year or so. I spend a lot of time to setting up M2 - ATX jumpers and Windows, but have no luck.
Does anyone know if, when the m2 is set to HardOff=Never, the 12volt rail goes off after the OffDelay?
I've got a fan hooked to the 12volt rail because my Intel d510MO doesn't seem to drive a fan. When the ignition is turned off the computer shuts down but the fan keeps running.
I can really only say what happens in my code...

I may be able to help if you can send me a picture or diagram of how you have the fan wired and a little more description of what happens when you turn off the ignition. Are you using your custom chip yet? Send me an email or a pm and I will try to help.
Is there a list of the LED error codes anywhere? I have my system on the bench and it's not turning on.
I'm getting a couple of long blinks followed by a number of 3 rapid blinks.
It's connected to a Motorola base station power supply that is putting out 15V, which is a bit high but should work fine. I've used it before.
email sent to blu. im ready to buy!
The error code is actually the long blinks and the patterns were referenced in the sheet that I sent with your pic. Here they are for reference:

1 long blink: Battery voltage under threshold
2 long blinks: 3.3V rail under threshold
3 long blinks: Mobo button press timeout (no PS_ON# low)
4 long blinks: Voltage rise timeout
5 long blinks: Mobo button press timeout (no PS_ON# high)
If you can determine which one you have, I will try to help you with it.
Thanks for posting, I must have misplaced the sheet and to be honest don't even remember getting one LOL.

Typing this it occurred to me that I may not have had the power switch wired up properly with the M2 on the bench. I'll check that.
Yep, pilot error. I had lines connected to the M2 for a power switch but on the other end of my octopus cable it wasn't actually connected to anything. So I think the blinkies were No. 3 above, although occasionally it would be only one blink, pause, blink, pause, then back to the 3 blink cycle.
Thanks for posting the list, though, that triggered the thought and made me realize my mistake.
