Hi
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
http://kernel.ubuntu.com/~kernel-ppa/mainline/
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
Cheers!!!
