My MagSafe Charger / Power Supply is not working

I am using mid 2009 13" MacBook Pro with 85W MagSafe . My operating system is Lion 10.7.4.

I heard a "click" coming from the direction of where my charger and just before and now its not working.

The light is not coming on the charger itself
No power is shown be coming into the computer on the Desktop toolbar either, nor does my computer that there's a charger plugged in.
I have tried the charger in a number of the different sockets around the apartment and still no joy
The transformer "block" is cold

Could this be a s simple as a blown fuse in the plug or something else altogether?

I need to fix this asap. No power = no computer. All help much appreciated. 🙂

MacBook Pro, Mac OS X (10.7.3)

It was an example of how to accomplish the goal without instruments. Just a very basic electrical circuit.

I had the same problem. Thought my macbook was done. However, it was just the 3 AMP fuse (red) in the removable plug adaptor that slides into the charger unit, which I did not know was there.

If you haven't a 3 AMP fuse to hand, then here's a trick I use: Just put some kitchen foil over the fuse. Make sure it's fully covered and strong enough not to rip once inserted. Then retry. If the charger lights up, turn off the power and go buy some 3Amp fuses.

This method IS frowned upon and NOT for permanent use!

However, I have done this testing method since the 70's and it has never ruined any of my electricals.
