Question

I have a toshiba satellite P105-S6167. Today's the first day that it stopped charging. For the past 3 days, I had to play around with the ac power chord to make the connector fit a certain way in order for it to charge. And within these 3 days, the ac power chord would only power my laptop. It wouldn't charge my battery. I had this computer for 1 year now and have been using it quite alot. I'm on it for about 12 hours a day straight 5 days a week since July 2007. I did purchase a notebook cooler in Dec 2007. I would like to know what my options are. Thank you.
