I was using the 737-200 and I was not using the APU or External Power/Bleed Air. After a while, the power went out. The battery had died. Nothing I did could get the power back, including loading the default C172 and getting power and then returning to the 737. I had to exit FSX and start again.

What I found interesting, was that I even switched between the 737-100 (-200, -200ADV, -200C and -200F) and noticed that the ADV was missing its landing gear (as if the activation had failed).

I have submitted a ticket. So Captain Sim will now be aware that this is happening (if they weren't already).
