It was charged but today it doesn't turn on suddenly.. I've seen similar cases with this but reset button doesn't work in this case. Now I'm charging it but it seems to have some trouble.. What can I do for it in the end?

Wow, suddenly it turned on!! The reason seems that the auto shut off function of DR1000S didn't work last time. So the battery was drained totally only a day. I always shut it off with this auto shut off function but it rarely doesn't work and I just guess my 1.5A charger has bad effect on it - the sensors of the device were freezed last time. I've bought and got a new charger today and now I'm testing it..
