thing about those terms is that, to me, they kind of imply that the computer is already running.. that it's already enabled.
This computer is off and has been sitting in storage for a while.. pretty much already disabled or deactivted... but those words don't really fit in that case either.
I'm just trying to say that if remove this motherboard, that computer will not be able to be used any more. But I want one word that sums that up.. maybe there just isn't one and I was imagining that I had one in mind?
