@Reimundo: like in your case, many of my LEDs do not work in the UEFI
mode. I ended up switching to the CSM where the samsung-laptop module is
not blacklisted. Bluetooth and all LEDs on my laptop work just fine in
the CSM. Until the samsung-laptop module is ported to the UEFI, our
Samsung laptops are not very useful when booted via UEFI.

Bug description:
  I cannot provide detailed log massages because laptop is bricked right
  now.

  If you have courage to try it select UEFI boot from bios and than try
  to boot laptop using liveusb (made form Precise Pangolin 12.04.1
  amd64).

  Laptop hangs up in black screen. If you force power-off, after it,
  laptop wont start. I mean it not event start bios, just black screen
  no sounds nothing.

  I filing this report, because i already bricked second laptop. At
  first i thought it was unrelated issue and laptop was fixed by
  warranty service (replaced motherboard), but after second time i quite
  sure.
