Mauricio Pretto, thank you for reporting this bug and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, as per http://support.acer.com/us/en/product/default.aspx?tab=1&modelId=2782 your BIOS is outdated. Could you please updated it and report back the results?
