The switches on the jacks are a known problem. You'll notice the switches on the side of the jacks with the pins that are resting on top of the foot at the bottom of the jack. Those switches don't make sometimes and need a bit of help. Go around and slide something (like a knife blade) under each jack until you discover the one that didn't quite make.
This happened to me once, I figured out which jack switch it was and it hasn't failed since.
When you get a chance, run your jacks out manually a bit, then retract them and see if the problem is still there.
Not sure I understand your battery problem. Your explanation doesn't quite make sense to me. You'll have to clarify the problem.
