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.
