Hello. I recently recieved a used Latitude 110L and the left click button doesn't work. I know they guy that owned it before and he wouldn't tinker with it and I wouldn't imagine that it would come into cotact with water or anything like that. I'm sure that it just needs to be cleaned out or something. Has anyone had this problem before or at least know how to pop the key out so i can check under it. I know what I'm doing around computer's but this is my first laptop.

Any help would be great! Thanks!
