I just wanted to post a conclusion to this thread. The power adapter in question has now completely died, less than 4 months! I knew there was something wrong with it, considering its performance was weaker than the 230w Chicony adapter. What's worse about this is that the company I bought it from will not replace it, even though I contacted them the first week I received it to tell them about the situation. I just wanted to let everyone know that I bought it from Adapter Family at adapterfamily.com and they do not stand by their product.
