The internet is stuffed with practical advice on how to fix various bits of laptops: try searching by model. I was really surprised what some people are prepared to do to help. Anyway, maybe you pushed the fan connector off (come to think of it if the fan was running you couldn't have). Can't see how you have done anything much wrong there. Hold the thing upside down and gently shake it ? I go for the big lump of fluff theory.
