Vincent, as per http://www.samsung.com/fr/support/model/NP-R525-JS01FR
an update to your computer's buggy and outdated BIOS is available
(05NS). 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 Confirmed.

Thank you for your understanding.

Title:
  Suspend to RAM freeze when wawking up with linux image 3.19.0-16

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Hi all,

  I noticed with my laptop samsung r525 running a fresh install of
  kubuntu 15.04 that if I close the screen, the computer goes to suspend
  to RAM but when I try to wake it up, the computer starts again but the
  screen does not turn on. Nothing is displayed and the screen remains
  turned off, including backlights (this is diferent from having
  backlights on again a blackscreen displayed on screen).

  I can reproduce the same behaviour by using the pm-suspend command
  from shell, or clicking "suspend to ram" into the exit menu.

  If I boot from the 3.19.0-15 kernel, everything works properly. I
  tried another kernel picked up from here http://kernel.ubuntu.com
  /~kernel-ppa/mainline/?C=N;O=D following this wiki page
  https://wiki.ubuntu.com/Kernel/MainlineBuilds?action=show&redirect=KernelMainlineBuilds
  (respectfully the v4.1-rc3-unstable and v4.1-rc2-vivid and I got the
  same problem each time.

  What is going wrong ?
