Problem with my Macbook Pro Charger
Sometimes when Electricity is turned back on by the power company, there is something called the surge.

It is a high Voltage spike, very, very short, and most appliance will survive, but some wont.

Aside of getting new charger, please buy a surge protector to prevent that happening again.

If you want to make sure it is dead, use a Volt meeter and check the chargers output pins.
