*** This bug is a duplicate of bug 795626 ***
https://bugs.launchpad.net/bugs/795626
intuited, as per http://us.acer.com/ac/en/US/content/drivers an update
is available for your BIOS (1.30). If you update to this following
https://help.ubuntu.com/community/BiosUpdate , 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
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
.
Thank you for your understanding.
