If I use a 15V 2.0A AC Adapter for my laptop, which officially requires a 15V 3.0A Adapter, and it works fine for a couple years, what sort of damage may I have wrought?

(My laptop battery doesn't play properly anymore, so I suspect that I killed it. Silly me, not paying attention to these things. I totally do NOT get electricity.)

Oh! I thought that the 3A referred to the actual power being supplied, not a limit on the power. Hrmmm. I really should take a course that explains all this stuff, like that Physics course I slept through in first year.

think of electricty this way...

Voltage is the strength/force of the electricity.
Amperage is the amount (quantity) of electricity flowing.

Yeah, that still doesn't make any sense. I've read many textbooks that say things like 'think of it like the amount of water versus the speed of water' and all sorts of other metaphors, but they still don't really click for me. I guess I'm just electricity-challenged.
