For an adventure I need a derelict ship found by the PCs to be unable to move due to empty fuel tanks (Not engine damage). I would like it to be possible to have life support running. I absolutely need to have the computer and the internal security systems (and a low berth) running. Is there any problems with that?
At a pinch, I can have the maneuver drives sabotaged instead of the tanks empty, but I'd really prefer not to, since it would contradict previously published information.
