'What do you think of...' versus 'What do you think about...'
I asked a similar question about these words before. ('of' and 'about')
And I know the 'of' version is old-fashioned in the following example:

Everybody is talking about him.
Everybody is talking of him.

But I'd like to know about these sentences:

1) What do you think of Laptops?
2) What do you think about Laptops?

Do you use the first sentence in real life (I mean nowadays)?

But I'd like to know about these sentences:

2) What do you think about Laptops?

Do you use the first sentence in real life (I mean nowadays)?

Answer

Yes, we use both, and there is no significant difference in meaning between 'What do you think of laptops?' and 'What do you think about laptops?'

Answer

Can't answer as to laptops specifically.  However, I asked a friend just the other day what she thought about her new smart phone.  If I had been asking about smart phones in general, I think I would have asked what she thought of smart phones. The "of" in that case indicating more of a category question as opposed to a specific question regarding her smart phone where I used "about".  Hadn't even realized I was making that kind of a differentiation until I saw your question.
