My power adapter for my Toshiba laptop is not functioning? - toshiba adapter

I have a Toshiba Satellite A200 series. Your adapter you do not charge my battery, but if you use the adapter, my roommate (who has the same laptop as me) that collects it.

Is there a way of solving my own adapter? "Or should I just get a new one?

It worked when stirring a little. But I will not damage it. If you can help, would be very grateful!
