My lg watch w100 is not responding after keeping on the cradle.

My lg watch w100 is not responding after keeping on the cradle.

My lg gw100 watch was working till last night properly.. i kept the watch in the tray and confirmed that it was charging , morning i found the black screen, watch kept in the tray with the charger plugged in and the watch is not responding. Now i want to confirm that there is defect in the watch or in the cradle.For this i should know the different pin voltages,then cradle defect can be confirmed, then battery of the watch can be attacked. There is no response from the reset/power button also as there is no charge in the watch.
