Topic: How do I shut it off (if a battery is attached)
1. I really would like to preserve the real time clock, so I added a battery.
2. There appears to be no off switch.
3. I keep getting kernel event messages and the 3.3v stays on for the bluetooth if I remove 5v power.
How do I keep the RTC running, but shut everything else off (among other things so I can swap the microSD)?
