I have managed to power down and back quite happily but I was getting 700 microamps consumption !! I had it comming alive with both RTC and external interrupts EXTWAKE must be set What did you get for current consumption? I did have a lot of stuff attached (JTag etc - which I did unplug) so I am builing another board bit by bit and measuing as I go. Owen Mooney
