[Closed] Exposure Enduro stopped working!

Help! Off on holidays tomorw and my Enduro (3 led 09 model) has given up the ghost.

I imagine it's going to be a 'send it back' problem and I'll have to manage without it (real pain) but just in case there's something I've not thought of:

The charger says it's 'full' (glowing green light)

The on button and indicator led works as it should (cycling through green-yellow-red etc)

But.. The light doesn't switch on.

However, perhaps most telling, if I whack the back end with the palm of my hand it lights up momentarily.

No rattle and no I've not dropped it.

It's less than a year old (so still under warranty)..Exposure mailed but I'm not expecting a reply over the weekend.

Googling (and searching the Forum) reveals nothing..
