Default Setting not saved when battery runs out

We have some 6950 the GPS one in uk.

When the battery dies and they are re-charged the bluetooth and phone do not turn back on. We have to manually turn them back. This is a problem in that our machines have a Kiosk mode to stop the user messing with the settings. So I have to let them turn of the kiosk mode turn on phone & bluetooth. Turn kiosk mode back on then they can use them.

How can I make them return to the state before the battery goes.

Keep them charged is not the answer I'm looking for.

Cheers
