Ubuntu – Cannot shut down on 13.10 and 14.04


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.

Best Answer

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.
