Re: X230 restarts when shutdown



Welcome To Lenovo Community


  Please follow the instruction as suggested below


First Install Ubuntu 12.04  in the system


Ensure the Live CD and USB drive is connected


Run following command


sudo apt-get install laptop-mode-tools



Open Grub File using text editor location   etc/default/grub



GRUB_CMDLIN   LINUX_DEFAULT="acpi=noirq quiet splash"


Then Run following command on terminal


sudo update-grub



If issue is not fixed then try updating the kernel maually from



Open a terminal and move to the directory where you have downloaded the Ubuntu 3.4 kernel packages. If the files are in /Downloads directory then run the following command.

$ cd ~/Downloads/




Then use dpkg command to install the packages, for example, here I assume the 32-bit versions of the packages. Run the following commands one by one and type the password for sudo access when prompted.


Run follwoing command


$ sudo dpkg -i  *.deb


If you see any warnings or errors while installing then try installing module-init-tools (latest version) first,


and try again now it should work. Restart your system now; by default it will boot kernel 3.4. To check the kernel version after booting,


open a terminal and type "uname -a".




Hope This Helps
