But it's not actually bricked. It might appear to be bricked, but it wouldn't be wise to make the judgment that it's bricked without at least doing some basic diagnostics such as putting the machine into target disk mode or testing an external display.
Bricking a piece of hardware is relatively difficult for a piece of software to do, even with firmware, because replacing the firmware is usually possible.
Speaking as a bit of a language Nazi (and geek), bricking is one of those terms that should be reserved for extreme cases where the hardware actually IS bricked. Using it for situations where the hardware is recoverable dilutes the meaning and makes it much more difficult to convey when hardware is legitimately bricked.
