Since my dad doesn't seem concerned enough to do anything about it (yet), and since it's been happening to me while I'm flying his airplane and it bothers me more, I'll ask for him:
He's running a single 10" Skyview with v7 software, and has a backup battery installed. Most of the time, it works properly, but sometimes when power is removed the screen shuts off immediately. This happened in flight yesterday when I accidentally shut off the avionics master, as well as when shutting down after a couple of other flights.
What would cause the battery to work sometimes but not other times?
