Perhaps the plague? No, not THAT one, THIS one:

Worth eyeballing since you already have the main board exposed.

Didn't think laptops used electrolytic capacitors...

They're surface mount, so you might not recognize them. *Google is your
friend....

Yes, but, although surface mount caps can be electrolytic, in a
notebook (none at all if it's a good design), very few caps are
electrolytic, if any, except in the external brick AC-DC PSU.

That's complete nonsense, of course a laptop uses electrolytics, and
lots of them to filter power throughout the unit. As jakedart said
they're surface mount units. Take one apart sometime & look.
