Hannah battery management and deep sleep current

My Hannah board takes 1.0ma during deep sleep. April only 20ua. Where is the Hannah power going? The regulator or one of the sensor chips which is disabled? I have noticed that after running code, the chips stay enabled and using power even after a cold boot of Imp. To reset them, one way is to power cycle the entire board by removing the battery. Still it takes 1.0ma. Is there any way to reduce this?

Yeah, you need to turn some things off. From memory, the rev2 temperature sensor defaulted to on. Possibly the fast clock on the IO expander, too.
