The second sentence is awkward. I think it is trying to say that she entered the room without letting him know. That is to say, without informing him. This means something quite different.
It is also ambiguous. The question is: know about what? It might mean that she did not let him know that she had entered the room. Alternatively, it might mean refer to something else that she kept to herself, rather than informing him. You would need to know the context in order to be sure of the meaning.
