[Bug 1040557] Re: UEFI boot live-usb bricks SAMSUNG 530U3C, np700z5c laptop

[Pavel Golikov]

Just bricked my Samsung 530u3c. UEFI mode was on.

I made a bootable flash from Ubuntu 12.10 64bit image using 12.04's usb
disc creator, then booted up, UEFI mode was on. (I've seen the black
grub screen insteard of syslinux), it booted normaly, everything was ok.
Then I tried to disable bluetooth and got kernel panic.

After reboot I see the black screen and nothing happens.

Such a pity. It takes at most 45 days to repair any device in Russia.
Only after that time I can request for new one or money back.

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.
