Seems to be the same question you asked last week. Here is a copy of my reply from then.

"I agree. If she is lethargic, doesn't eat, and stays in a cool dark place she is likely starting Brumation. I would leave her alone and weigh her weekly at first to make sure her weight remains stable. If she remains stable I would disturb her less often. I check my brumating animals every 5 weeks."
