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.
