13.10 has been re-installed on my i3. I cannot shut down or log out. The power button menu does not help and sudo shutdown -h now also did not help. Can you advise? Other suggestions to my query have been tried. I am still unable to log out or shut down.

Computer spec:

CPU: Intel® Core™ i3-4130 CPU @ 3.40GHz × 4 ; Intel® Haswell.
Motherboard: Intel Round Lake dh87rl Lga1150

If I select and click on Shut Down and hold down the power button for a count of 10, the machine will power off.

I have pressed F2 to Enter Setup when the machine reboots. Nothing happens. F7 to Enter Bios also does nothing. F10 to Enter Boot Menu made the PC freeze. I had to force a shutdown.

Sudo shutdown -h produced following message. The link is on Imgur: imgur.com/ud9ECnA

I Upgraded from 13.10 to 14.04 on 21 April 2014. The machine still does not shut down. I have to hold down the power button or 14.04 automatically reboots. My kernel is 3.13.0 -24-generic #46-Ubuntu SMP Thu April 10 19:11:08 UTC 2014 x86_64 x86_64 x86_64 GNU Linux

sudo shutdown -P now or sudo poweroff and sudo shutdown -h now do not help. Halt -p produces:"halt: Need to be root." sudo halt makes the machine freeze. sudo halt -p does not help. The machine reboots immediately.

I did not know how to enter Bios. Wakeup on Lan is disabled. The problem is solved.

    did you tried sudo shutdown -P now or sudo poweroff? Feb 10, 2014 at 3:20
  • These did not help. The machine automatically restarted. Feb 10, 2014 at 21:08
  • What happens when you try those commands? Do you get any output?

  • What is your motherboard, and did you change anything in grub before having this problem.

The shutdown command does not work if wake on lan is enabled in the bios (see https://communities.intel.com/thread/45667).

If you have to use wake on lan use halt -p instead of shutdown.

  • halt -p does not shut down. If I press F7 to Enter Bios does this not do anything. Mar 15, 2014 at 12:00

Shut Down:

sudo shutdown -h now


sudo halt


sudo halt -p


sudo reboot
  • The Shut Down attempts failed. In each case the PC automatically restarted. On sudo halt the machine froze. R E I S U B and alt/ printscreen failed and I pulled the plug out... Feb 10, 2014 at 21:07

To shutdown I use the brother of reboot:

sudo poweroff
  • did you see the comments this and this? Feb 11, 2014 at 12:16
  • sorry. I missed that. Anyway... didn´t you saw any message in the terminal after the command? any error or complain from the command to use it as a clue? after a poweroff your pc reboots??? are you sure?

  • @AvinashRaj I lost the thread of the help-discussion. I re-entered sudo poweroff, sudo shutdown -P now, sudo shutdown -h now. The machine shut down immediately and rebooted immediately each time. Before 'sudo shutdown-h now' the following appeared in the terminal: "$ down vote accept No command 'down' found, did you mean: command 'cdown' from package 'cdtool' (universe) down: command not found $ shut down: shut: command not found."
