bastien, as per the release notes from http://h20564.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=7834518&swLangOid=8&swEnvOid=4192 an update to your computer's buggy, insecure, and outdated BIOS is available (1.11). When you update to this following https://help.ubuntu.com/community/BIOSUpdate does this improve the situation?
For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Also, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid.
