+Q13: When I plug the charger in my Recorder, it doesn't immediately start
+     charging the batteries. And when I plug in the charger when the Recorder
+     is turned off, it turns itself on and starts charging in the Archos
+     software? What's up?
+A13: There is a switch in the DC IN jack of the Jukebox - when a charger (or
+     whatever) is plugged in, the unit is powered on, even if the charger
+     is not plugged in a mains outlet.
+     
+     If the charger is providing power at this point, the Archos firmware
+     located on the FLASH ROM does not load a new firmware version (like
+     Rockbox) from the disk, but goes into charging mode instead. You can
+     use this feature to get to the Archos charger if you want to.
+     
+     When Rockbox is running on the Recorder (the device has been booted
+     without the charger) it's power management code runs once per minute
+     (thus the charge level and charging status is only updated every minute).
+     If the battery is not full, it will start charging. If the 'deep
+     discharge' mode is enabled in the settings menu, it will start charging
+     only when the battery is almost empty.
