I would be unreasonable. The power state appears to me as highly asynchronous to program execution. I see no explicit guarantees on how the state is retrieved or synchronized, without synchronization the state wont be properly updated. We know that the computer was of at some point, so it starts of as undefined. Given undefined as starting state and the lack of update guarantee we can assume that it will always return an undefined value. This opens up a lot more optimization possibilities than assuming a 1.
