Two light tan, near left bottom corner, ~1/4 distance to
top edge and ~1/8
distance to right edge, with brown polarity bands,
opposite polarity, bands
out.

Without part numbers, it's meaningless.

I see at least 3 on the bottom view, one near the top
edge center and two
near the bottom edge center, partially hidden by a wiring
bundle.

Any cap over 10 uF will probably be electrolytic.

Wrong.

Actually most laptops use tantalum polarized capacitors
which are a type of electrolytic capacitor. What they avoid
are the more common aluminum electrolytic capacitors.
Ceramics are available in low voltages at quite high
capacitance values, but I have yet to see one over 10 uF.

Nope. There are wet tantalum capacitors (that exist), but nobody uses
those in laptops. In laptops you find surface mount dry tantalums
among other solid types, not electrolytic at all... again, this refers
to semi-modern laptops, not something really ancient.
