[stblack <1040557@xxxxxxxxxxxxxxxxxx>]

I have installed ubuntu on my NP770Z5C setting "CSM OS and UEFI" and disabling Fastboot and secureboot (Windows boot is working). Quite all seems ok.
I would like to have also che Backlight keyboard functioning, but not bricking all.
Is it possible to use what is listed in this page (https://bugzilla.kernel.org/show_bug.cgi?id=62941) and have it working?
Could someone help me  ?

Thanks.
Stblack

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.
