2 week old MacBook Pro not charging

I bought a MacBook Pro only 2 weeks ago, and to my surprise, I am already having problems with it. Although the top tool bar shows the battery as charging, and it doesnt lose power while the power cord is connected, it is not charging. The battery power is stuck at 27%, unless I unplug the cord, which obviously causes the power to drain.

Why wont my brand new MacBook Pro charge?
