Displacer, thank you for reporting this and helping make Ubuntu better. As per http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdHome/?sp4ts.oid=5359417&spf_p.tpst=swdMain&spf_p.prp_swdMain=wsrp-navigationalState%3DswEnvOID%253D4059%257CswLang%253D%257Caction%253DlistDriver&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken#BIOS an update to your BIOS is available (F.28). 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

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

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Once the BIOS is updated, then please mark this report Status Confirmed.

Thank you for your understanding.

There is no .iso file in this executable after cabextrat, rom.cab and rom.bin only. Dont know how to upgrade bios in this case, are there any suggestions?

Displacer, the = HP = section was written in 2009. I've just updated it to reflect this.

This issue seems fixed in at least ubuntu 15.04 with 4.0.0-4 kernel or maybe even in an earlier kernel and ubuntu releases.
