feytullahede, thank you for reporting this and helping make Ubuntu better. As per http://h20564.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=5405097&swLangOid=8&swEnvOid=4158 an update to your computer's buggy and outdated BIOS is available (1.31). 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

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. As well, you don't have to create a new bug report.

Once the BIOS is updated, and the information above is provided, then please mark this report Status New.

Thank you for your understanding.
