I have two beautiful 6 year old (approx) Russian tortoises and have one that insists on hibernating. The female is doing well, active, and feeding daily. The male is not interested in anything and simply sleep constantly. His weight is good and he is not losing.

I do bath him no less than once a week.
I have them in the reptile room in the house - not a cool place.
I have even tried putting him in the hot spots - he simply leaves them and goes to sleep somewhere.

Any suggestions on how to wake him up?
