Mark, as per http://support.lenovo.com/us/en/products/laptops-and-
netbooks/lenovo-b-series-laptops/lenovo-b50-70-notebook an update to
your computer's buggy and outdated BIOS is available (2.08). 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 provide the 
output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, and the information above is provided, then
please mark this report Status Confirmed.

Thank you for your understanding.
