I have a laptop (Aspire 1) that says the battery is fully

Well, there are a few possibilities. The most likely is the battery
has lost almost all of its capacity. Does the battery have a "fuel
gauge" on it? Can you check it while charging and after you try to run the
computer on battery power?

It is also possible that the battery management circuits on the
laptop have died, so it either fails to actually charge the battery
or can't draw power from a good battery. It is even possible the
battery-laptop contacts are dirty or bent and not making a connection.
