In my previous mail on EC commands (EC can wakeup the CPU) I asked if we 
want the EC to wake up the processor when the battery capacity decreases 
by some x% and what x should be.  Or should we set a single battery trip 
level?  I was planning on a battery at critical stage alarm as well.

What sort of thing would we do with knowing that the battery decreased 
from 50% to 40%?
