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

[Angel Garcia]

At my university, we bought several Samsung Series 5 laptops (NP530U3C
model). Our students bricked four of them when installing Ubuntu. I sent
them back to Samsung that repaired them promptly by warranty service.

I don't know exactly what Bios configuration neither what Ubuntu version
each student tried. I only know they installed Ubuntu from a USB stick.

Now the good news:  I have just installed ubuntu-12.04.1-desktop-i386 in
five of these laptops without problem. The procedure I followed was
shrink Windows, disable UEFI in BIOS, and boot from a ISO CD with Ubuntu
(not a USB), with an ethernet conection.

I want to remark something strange: on two of these laptops, after
installing and do a power off cycle, both laptops frozen at BIOS screen
([F2] and [F4] message visible, but irresponsive to keyboard). However I
do not power off the laptop because I did fear to brick it again.
Actually, I waited for around 10 minutes, and magically the laptop
resumed itself. But after a few seconds it frozen again with a black
screen, and after 10 minutes it resumed the boot procedure (Grub
screen). And now they are fully funcional as in Linux as in Windows.

(The other three laptops were installed flawlessly, without any freeze
at all).

I suppose that these frozen lapses can be due to an automatic BIOS
upgrade. If so, power down the computer at this moment (as many of us
did) will brick it.

bios version = micom version = P03AAJ

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.
