Probably a slipping belt or loose tensioner. The alternator runs on the same belt, along with the water pump, and AC compressor. If the water pump was locked up, you'd definitely lose the belt, and then get the alternator light.

At 80K, it's probably due a new belt soon anyways. That would be both cheap and easy to replace. It's sort of a pain to get to, but it might be a good idea to pop the front engine cover and check to make sure it's not more serious before you put too many miles on it.

This is about what the engine should look like if you have the cover behind the seats off.
