2011 Volt 110V Charger Issue

I have been using my 110V charger for the past year with no issues, but starting yesterday it no longer works -- the flashlight stays lit all the time (as if the trigger is being pulled), and the Volt doesn't beep when the charger is inserted. I tried unplugging it for 15 secs but same result.

Anybody else ever experience this issue or know of a fix? Any idea what a replacement charger will cost from the dealer?

(Note: this charger is the new one I got from the dealer in 2012 after they recalled the original 110V chargers.)
