    Exclamation Laptop automatically reboots after shutdown

    I recently bought a Thinkpad S431and installed 13.10 onto it dual booting with Windows 7. When I'm in Ubuntu I cannot shut down the laptop. When I shutdown the computer stays off for about 2 seconds before automatically booting itself up again. It does not do this if I shutdown in windows.
    I made sure I have all the latest updates from the software updater. I tried shutting down by using the commands sudo halt and sudo shutdown -h but there was no difference. I also tried disabling wake from lan in my bios as per recommendation of a forum post I found on google with a similar problem, but that did not work either. It is a pain to have to reboot into windows in order to shutdown the laptop.

    Here are the specs of the laptop if that matters

    CPU: Intel Core i5 3427U @1.80GHz Ivy Bridge 22nm
    RAM: 4.00GB Single-Channel DDR3 @ 798MHz
    Motherboard: LENOVO 20AXCTO1WW (CPU Socket - U3E1)
    Graphics: Intel HD Graphics 4000
    Storage: 119GB SAMSUNG MZ7TD128HAFV-000 (SSD)
    Audio: Realtek High Definition Audio

    You might try
    Code:
    sudo shutdown -h -P
    That adds the power off (-P) to it.

    I seemed to have fixed it. Using the steps on this page. http://linuxg.net/computer-reboots-i...-ubuntu-12-04/

    It appears to be working after using the command
    $ sudo apt-get install laptop-mode-tools.
