Daniel Hahler, as per http://download.lenovo.com/express/ddfm.html an update is
available for your BIOS (1.39). 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
Thank you for your understanding.
