Till Kamppeter, as per
http://support.lenovo.com/en_US/downloads/default.page? an update is
available for your BIOS (1.57). If you update to this, does it change
anything?
If not, could you please both specify what happened, and provide the output of
the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
Thank you for your understanding.
