Hence, as per http://us.acer.com/ac/en/US/content/drivers an update is available for your BIOS (2.12). 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 Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .
