My original adapter had a short where it plugs in to the back of the computer, so back in June I bought this one to replace it. I too got a cheap knockoff, but I figured it wouldn't make any real difference. I was wrong. I don't use my computer much, maybe a few hours a week, and my original adapter lasted over three years. This one quit on me after less than 5 months! Save yourself the time and money and get a better adapter from somewhere else.
