My calculator has just stopped too. It just powered down all of the sudden. I was not updating anything and it wasn't plugged in. The battery also indicated 75%.
I tried all the reset options mentioned in this thread to no avail. Is there anything else I can try?

I remember to read similar situations in other posts, and I would recommend to do a full battery charge (at least 6 hours) using the official charger to start with.
Then I would try again the above procedures.
