I find it hard to believe that Hong Kong has a climate that will put a RES into true hibernation. I've been in HK in the late winter/early spring and have seen turtles basking (at Kadoorie Farm, I think the name was) in really cool, windy weather. But I don't think that the temp ever gets like it does here in New England, where native species do hibernate.
For some species, hibernation is recommended for breeding purposes. And, I've read that in some cases it can increase longevity. I've never heard that hibernation is necessary for a RES, though.
What it sounds like your turtle may be doing is going through a (rather long)cooling period. Some people do do this with their turtles, but I think it has to be done with some care.
I would consider following your vet's advice in that I would alter your turtle's set-up to keep the climate more like your turtle would have in the warmer months. By warming light, I'm assuming your vet means a heat lamp, and you can provide heat with a regular lightbulb. A UVB light will give your turtle some of the rays he would get if he were able to bask outdoors. And, a water heater would keep the water temp consistent.
Just curious, but your turtle has "hibernated" for the past 5 years? What was he like, physically and behaviorally, when the weather warmed and he woke up?
