New SB1 will not turn on after inserting in cradle

My 2 new SB1's which came as normal showing the standard sleep mode screen will not turn ON after insertion into

cradle?They make the correct beeps but the sleep mode screen stays.The units do charge up, I tried a reset but still no change.

The screen beeps when you touch it like the unit is working in the background. I have a USB back if there is a file I need to change.
