Anmar Oueja, as per http://download.lenovo.com/express/ddfm.html an update is available for your BIOS (2.59). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and just provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
