boukeas, thank you for reporting this and helping make Ubuntu better.

As per
http://h20564.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=6943803&swLangOid=8&swEnvOid=4192
an update to your computer's buggy and outdated BIOS is available
(1.16). If you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it change anything?

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, 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.

Thank you for your understanding.

Title:
  Screen periodically goes black for a second

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I am using Ubuntu 14.04.3 on a HP ProBook 430 G2/2246. It is often the
  case that my screen goes black for a second and then recovers. It is
  my impression that this only happens when the computer has been idle
  -- even for a very short time -- so I have disabled screen locking and
  dimming and I have also removed the gnome-screensaver package, yet the
  problem persists.

  I took a look at /var/log/syslog and discovered an identical set of
  error messages (dump traces, mainly) for every time this happens. I am
  attaching a file with this set of messages.
