  • M2-ATX does not cut off power(hardoff)

    Hey guys, I have a problem that everyone seems not to have.

    Background: upgrading my jetway Motherboard to a new zotac ionitx-f-e motherboard. The M2-ATX works flawlessly with the jetway on P1
    (5s delay 45s hardoff). I'm using a 12V ac-dc adapter (rated at 6A, plenty of power), simulating ign with 12V switch. M2-ATX was purchased here, from the mp3car store around feb, 2008.

    Problem:

    (A) ign on, wait 5 seconds, computer turns on
    (B) ign off, wait 5 seconds, computer hibernates, then turns off
    (C) ign on, nothing happens

    Further testing:

    - computer draws at a peak when booting ~2.2A, ASSUME: ac-dc adapter isn't the problem

    - when m2-atx turns off (B), it is still drawing 100 mA after comp hibernates. ASSUME: is the 5VSB line still on.

    - 12 hours later, M2-ATX is still drawing ~100 mA. ASSUME: M2-ATX never cutting off all power.

    - If I unplug the ac-dc adapter (cutting off unswitched 12V to m2-atx), and ign on, it will boot up normally (A) but get stuck at (C).


    My conclusion:

    In the manual, where it states the mode of operation, the m2-atx is stuck right after sending a signal to mobo off.
    It is NOT turning off the 5VSB line after "hardoff" seconds (45s in my case). Therefore, not detecting a switch on the IGN.

    What's the deal? I thought M2-ATX will shut off all power DISREGARDING the state of the motherboard. It cuts off power on my jetway mobo (using only 7mA
    instead of 100mA), AND detects ign on after it shuts down.

    possible fixes?
    - bios settings? nothing in the bios ive changed helped
    - windows xp sp3 acting weird? upgrade to windows 7?
    - bad motherboard? works fine without m2-atx..
    - bad m2-atx? works fine with my jetway mobo..
    - motherboard keeping PS_ON or PS_OK signal on ATX power connector? I thought M2-ATX ignores the state of the motherboard for hardoff...

    Any help is greatly appreciated, as I am baffled... and outraged. Thanks

    Having the exact same issue. Using a Zotac as well. Just hopped on here to see why I have a dead car battery.

      Still having issues where the m2-atx would sometimes work (like its supposed to) with the zotac, then 10 minutes later, same issues (I didn't touch a thing) so I emailed mini-box,

      the rep said the following:
      " You have a strange issue. I suggest to try another OS for the start. As both the motherboard and the psu work ok separately, i suppose the problem is not from one of them, maybe the OS or some incompatibility( never had with Zotac boards)."

      I am currently running windows xp sp3. Everything is running fine on XP, I do not want to switch (mostly because iguidance v4 would break). Anyone got an M2-ATX working with a zotac ion f-e board on xp or win7 or linux?

        actually is .1a draw unusual? i think thats just what they draw while off.

        it actually seems to me like your motherboard is not set to wake up from hibernate via the power button. check your bios settings.

          My M2 clone doesn't have this problem, but it DOES draw about 3ma after hibernate. The LEDs are still on on my USB hubs. I draw the 5V power for the hubs via a hard drive power connector, which I would have thought would cut off upon hibernate.

          Can somebody correct me?

            @ jmullan99, actually 3 mA after hibernate is rather good. I'm assuming that's the current draw for the LEDs. The idle current for the m2atx (Off, waiting for ign to turn on) is about 7 mA. Interesting to see how the m2atx clone is more efficient!

            trader007 is right.
            ATX certified power supplies leave the 5VSB (up to 100mA. Which will drain my battery within the weekend) on so that the mobo can still sense a power switch push (not so for 'intelligent' automotive power supplies like the m2-atx). Also, its not my bios setting since I was able to wake it back up with another power switch successfully.

            Unfortunately, my power problems are still unresolved.

              To all of you having power problems, I believe my custom code is a solution. I have verified that it will perform the offdelay and hard-off functions properly as well as having an improved battery voltage monitoring scheme. Check it out in this thread and let me know if you are interested in buying a preprogrammed PIC to update your M2:

                Interesting indeed. But.....

                ... at least on my clone, 5V is still alive since the LEDs are on. But 3ma would take quite a while drain a good battery.

                I would love to try your custom code. Alas the controller on the clone is soldered in. I'm sure I could take the time to disassemble the box, remove the PSU, carefully unsolder and remove it, solder in a socket, put in your controller and try it out. Even then the board is just different enough that it may not work. For instance, there are no jumpers (although it looks like there are pads where some could have gone). There is another connector along side the connector for the CPU power switch, it "may" be for an amp trigger, but I cannot know (it was not well documented).

                  Thanks for the offer blutdi09 but I think I just found my own solution using an arduino and running the m2atx in "dumb" psu mode. I have the arduino controlling other devices as well, so thanks again for the offer

                    so .. is there a real solution for this ... about to buy a M2-ATX and a Zotac IONITX G-E...


                    Thanks

                      InsaneQc, I think my power problem is an isolated issue. I've poked around the forums and found that everyone else that owned an M2-ATX were having the opposite problem of cutting power too early.

                      Also, I have an "old" version of the M2-ATX when I bought it in Feb of 2008. The M2-ATX has gone thru several revisions that seem to make it better.

                      Good luck on your install

                        are you sure it is a isolated problem for your F-E Deviant .. because my Friend has a D-E Works Perfectly and bought his M2-atx around 2008-2009 Too..

                        But I wan't to buy a G-E But not sure because you and JQ-Fletcher has the same isssue
                        This is pretty much the same MB but why the M2-atx would work perfectly with your jetway MB... Maybe Motherboard/M2-ATX Compatibility issue ?

                            I know this is bringing up an old thread, but i'm actually having the same issues. My M2-ATX is not doing a hardoff and is draining my battery with in an hour. I know i've got a weak battery at this point, but it's obviously draining it. If it matters, i'm running an Intel D525MW.

                              having the same problem here. Doesn't seem to do the hardoff .... had to unplug main power as my 3rd dead battery before my part time job is not fun
