I have been trying to understand the usage of "think of" and "think about" for some time and would like to know whether I got it right:
I am thinking about/of changing a job. What do you think about/of him?
No difference in meaning.
It is broken, I need to think of a possible fault.
I think here I do not know the fault yet.
It is broken, I need to think about the problem.
I know the problem already and I am thinking about it/fixing it.
