PC Won't Power Off When Halted

  • Might need an even newer kernel. There are plenty of posts on this forum about using 4.x kernel on OMV 2.x

  • Also found out a couple different things. First one is I tried a different home server on it and it does the same thing. Secondly I found out that after I halt it and it "powers down" if I hit the power button it reboots, this is good because before to get it to boot again I had to unplug it and reset the CMOS. I believe it's no longer a problem involving OMV, either it's normal behavior for that motherboard or it's some sort of hardware incompatibility.

  • Send Supermicro a message and ask them what they recommend. I have two Supermicro boards and both shutdown fine.

    I contacted them and they even gave me a newer bios that I didn't see on their website but alas that and the other suggestion they had didn't change anything. I ordered a Supermicro ATX PSU off of Ebay and received it today, as soon as I get some 8 pin power cable extensions I ordered I'll try it out.

  • Ok I think I have it fixed and it wasn't OMV's fault.


    I bought some new heatsinks the other day and during install I had what I thought where power supply/motherboard problems. Anyways after about 5 hours of troubleshooting I found out the problem was something I didn't expect, during the initial motherboard install I left in some standoffs that didn't match any motherboard holes and put electrical tape over them to provide some extra support for the motherboard. As soon as I removed them it started behaving correctly and a unexpected benefit is that my power off problem is fixed, the power button behaves like it should.


    The only reason I can think of why those standoffs caused a problem is that they were putting to much upward pressure on the motherboard, I know it probably wasn't a shorting problem due to using electrical tape.
