Will Cooke, thank you for reporting this and helping make Ubuntu better. As per http://download.lenovo.com/express/ddfm.html an update to your BIOS is available (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 provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
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.

I have it set up so that I use both monitors. When I undock the laptop, and so remove the external display, the laptop panel brightness goes to minimum and cannot be made brighter either via the function keys or the system settings slider.
