Is a laptop power supply "intelligent" in that it adjusts its own behaviour based on the state of the laptop's charge (whether it's the laptop telling the PSU what to do or the PSU actively detecting its state)?

Or is it just a transformer?

Within a few days of noticing the laptop doesn't stop charging when 100% full, I've seen a little break in the cable rubber with exposed wire that may or may not be related. I'd don't want have it repaired or buy a new one if I thought it would not fix the problem.
