Ubuntu – Ubuntu 16.04 won’t shutdown

acpiapicpower-managementshutdownsystemd

When I try to power off Ubuntu 16.04 LTS on my MSI GS60, the laptop will not shut down. Reboot works fine though. I have removed the quiet splash parameters for grub so I can see the output. When I try to power off the laptop, it gets to:

[ OK ] Reached target Shutdown
[ OK ] Reached target Final Step.
Starting Power-Off...
reboot: Power down

and it stays like that forever. I have tried the Sys Req key trick to make it poweroff and it doesn't work.

I have tried to set the following in /etc/default/grub and then run update-grub

  • acpi=off –> won't even boot
  • noapic –> will shut down, but keyboard doesn't work at all
  • nolapic –> no difference
  • apm=power_off –> no difference
  • reboot=bios,force,efi,warm, etc… –> no difference
  • irqpoll –> no difference
  • acpi=force –> no difference
  • xhci quirks on grub config didn't help either

This known bug is a similar issue, but unrelated since in this case the system reaches the "halt" status but doesn't shutdown.

Best Answer

I believe mine was a bit different because it was reaching the target [ OK ] Reached target Shutdown. I was forced to disable USB 3.0 in BIOS and now I can shut down normally.
