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

[sunday]

Bricked Laptob today (2012-12-18).

*Model: Samsung NP530U3C-A01E

*Note: Prior to bricking: Installed Xubuntu 64bit (12.10). No Problems
occured during the first three weeks of usage (including kernel update).
The only thing I noticed was battery/power status misinformations.
(likely the already mentioned acpi bug..)

*Tried to reinstall to SSD  today (laptop features a hybrid harddisk)
for which I had to enable EFI. At the same time I disabled fastboot in
BIOS.

*EFI in BIOS was enabled so I was able to boot from external USB
Harddisk (as booting image from USB stick did not work with the usb
stick employed today).

*everything (Installation to SSD and booting/shutdown) worked fine.

*Bricking the device: Turned off the device (with an usb stick in right
usb 2.0 port). Powered device back on with usb stick still inserted.
During BIOS stage (before bootloader got loaded) i pulled the USB stick
out of its slot. After that, the laptop seemed to have froozen. Now I am
able to experience the black screen situation as described above.

This is no Linux/Ubuntu Bug. Just wanted to inform other people not to
touch boot devices in BIOS stage as this may just as well brick your
laptop.

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.
