New Surface 2 not starting without charger attached

Posting this on behalf of a friend who just received his Surface 2 (32GB version) yesterday, after having ordered it a week ago.

The problem is the tablet works absolutely fine and perfectly when connected to a charger. As soon as the charger is disconnected, the tablets shuts off and won't start until it's connected to the charger again. He's checked for updates and installed all the ones that were available. He's even reset the device (hard and soft) but the problem persists.

Any tips/suggestions would be very welcome.

Thanks.
