Right, you've got it the wrong way round - the goal is turn off the
widgets that are holding the device on.

Currently.  And to be honest I would have expected that the behaviour
would be the same with widgets on regardless of the bias level so we
probably want to fix that which would cause the same problem resurface
even if it were bodged around for now.
