Check your BIOS settings. everytime I've had this issue it was because of bios settings. In fact a foolproof solution would be to use your BIOS's reset functionality.

Tell me if this worked, cheers!

  • Made it by "restore default" option in my bios - problem is not resolved – a.kozubenko May 12 '17 at 10:14
  • type sudo shudown into a terminal does it still reboot? – tatsu May 12 '17 at 10:18
  • sorry for long time away, yes I did it - the same result – a.kozubenko May 12 '17 at 11:47
  • How is that not a hardware issue then? how can software trigger the hardware to turn on by itself? check all bios options for anything unusual, if you could edit your post to accomodate pictures of all your BIOS menus, check for faulty hardware. The power button or reset button or something else could be faulty/stuck/experiencing static or short circuits. And most importanly power down the PSU or unplug the computer from the wall completely wait 20 seconds plug it back in and see if it turns on by itself. – tatsu May 12 '17 at 11:51
  • With hardware everything should be okay. There was a Windows two days ago and all were ok.

  • try unticking all those boot options : USB floppy ect. and try the unplugging test i mentioned above. – tatsu May 12 '17 at 12:23
  • I did what you say. I turn off laptop with poweroff button it will not start.

    also I found in bios Wake-on-Lan option and turn off it. Situation now: for suspend it is work ok. Laptop is going to sleep and does not start till I press the button. But for shutdown it is reboot

  • did you try unplugging the power cord waiting 20 seconds then plugging it back in? does it turn on by itself? if not once you turned it on yourself and try to shutdown does it still turn on? – tatsu May 12 '17 at 13:30
  • I tried unplugging the power cord. But I could not wait 20 seconds because it started to turning on. Should I turn off battery?

    If I try to shutdown when power cord is connected - as result will be reboot

  • oh, it's a laptop! yeah remove the batery as well. the goal of this exrcise is to discharge the components and see if as soon as current is available again it takes that as a cue to turn on. – tatsu May 12 '17 at 14:06
  • So, what I did now: 1. turn off laptop 2. remove battery 3. Wait 30 second 4. Install battery. Result I do nothing but it started to turning on in 3-5 seconds – a.kozubenko May 12 '17 at 14:15
  • see that's what i meant. ubuntu is now guaranteed to be entirely absent from fault. This is now with 100% certainty a hardware issue. Powered down soft (even that concept is false) cannot issue current signal to the motherboard. It cannot turn the computer on. update your OP with every screen from your BIOS photographed. – tatsu May 12 '17 at 15:00
