I second, third and fourth what the last few posters have advised. Send it for repair, along with the explanation.
I suffered precisely the same circumstances as you and DJI have repaired it under warranty. If UPS tracking is to be believed, I'm due to get it back tomorrow. As an aside, kudos to DJI here. After the horror stories of people waiting months for repairs, DJI Europe (in Holland) have turned my aircraft around within a week... so including time in shipping (from/to the UK), I've only been without it for little over two weeks. (It was a pain initiating the whole process though, taking about as long in email toing & froing before actually getting to ship it off to The Netherlands. It was also a pain forking out 20 quid for shipping, but with my local stockist over 200 miles away?! )
Also, I think I have to make a passing comment here for all you depleted battery doubters out there. Whether this might be is a DJI or a user dereliction, I don't know. All I can do is relay my experience as detailed in this thread... http://forum.dji.com/thread-34033-1-1.html, which I created at the time my aircraft "just fell out of the sky".
In 85 flights, I can't really remember flying on a battery that was more than a few percent below 100%. The time I made this fateful flight, the battery was at around 75-80%, having been fully charged about 3 or 4 days before. What I believe might be critical in this issue, is it had began its sequence of auto-discharge and would have been approximately half way in its journey to under 60%. Does this intelligent little battery plot revenge for being woken from its discharging state? Well perhaps, but what I think is more likely... is its "intelligence" within this discharge phase becomes a bit confused until it's been kicked up the backside with a charge back up to 100%, whereupon all its measured parameters become realigned.
So... was my aircraft's failure coincidence?? ... (85 trouble free flights on 100% batteries, remember!)
Anyway, whatever... anyone here might guess I won't ever again chance flight on a battery that has been left so long after a full charge that it has entered into its discharge phase.
Edit to add: I have all my batteries' time to commence auto-discharge set to 3 days... just in case anyone was wondering...
