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.
