737 elevator

[allflight57]

Can someone explain how on the 737NG, while the aircraft is in a cold and dark state, the elevators remain in the neutral position, how is this done if the hydrauics are (obviosly) depressurized? Im assuming it goes into manual reversion after hydraulic pressure is no longer available, so wouldnt the elevator droop downwards kind of like ERJs? Also one more question, how are the flight controls proteced from wind gusts if the hydrauics are depressurized?

Thanks,
Tyler
