Title:
  Resume from suspend does not work on Samsung NP305V5A-S06 (AMD A6)

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Resume does notwork on this laptop:
  Make/Model: Samsung NP305V5A-S06
  CPU: AMD Quad-Core A6-3410MX Accelerated (1,6 GHz, 4 MB)
  Video: AMD Radeon™ HD6540G2 Dual Graphics
  VRAM: 1GB DDR3

  Full spec. (it's on Russian, sorry):
  http://www.samsung.com/ru/consumer/computers-
  peripherals/notebooks/essential/NP305V5A-S06RU-spec

  OS: Kubuntu 12.04.

  
  The problem is very similar to the one in Bug #925646, but I'll repeat them here as well:

  
  The desktop correctly goes to suspend, with fans silenced, audio turned off and screen output stopped. Neither the keyboard nor mouse (USB both of them) are able to wake the machine. On attempting to resume with a single short touch of the power button, the fans spin up to full speed and stay spinning at full speed, the power light comes on as expected, however the screen remains black. Moving the mouse or pressing keyboard keys does nothing.

  Did the machine break while going to sleep or waking up?
  - Waking up (resume)

  Is it reproducible?
  - Yes on 10 out of every 10 sleeps, it failed to resume

  Did it work before?
  - I've not tried any other distributions/versions of Linux n this laptop before. So, I can only say that it doesn't work in Kubuntu 12.04.

  Do you end up with flashing Caps Lock light or similar?
  - Don't have these indicators on my keyboard.

  The computer does not reboot until forced by holding down the power
  button etc.
