rmcd, 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 (9SKT81A). 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.

For me, this only occurs after the display has been blanked for a period of some hours (typically overnight).
