My Macbook Pro Power Brick is faulty and blown the fuse in the extension cord. Since it is protected under the Apple Care warranty, Apple do offer a replacement for the power brick and extension cord.
Update: So I went to replace my faulty power brick at Eserv Wheelock Place. They did replace the 85W Magsafe Power Brick, but did not replace my 3-pin extension cord with the blown fuse. Maybe it is stated in the Apple Care Terms and Conditions that the extension cord was not part of the warranty, but I find it interesting that why Apple did not give me a new fuse so that I can have my complete set of the charger kit. Nevertheless, I managed to salvage a fuse and get the power brick up and running.
