Task: Sentiment Analysis
Input (English): Review: The adapter worked fine for my power book g4 for a few months and then it broke. Nothing physically happened to the adapter for it to break, but suddenly it just wouldn't charge any more. What's interesting is that the blue light on the brick goes on when plugged in to a power source, but if I plug the cable that attaches the computer to the brick in, the light goes out and it doesn't charge. 
 Polarity: Negative
Output (English): True
