Yes, some computers in the 6100-6400 series had issues. According to Apple and to my experience, none of the later ones did. Notably, some people on the forum claim that they had issues that were resolved with the battery change. Noting that the battery change would also reset PRAM in most cases, I am not sure whether this was a correct expression of their troubleshooting experience, but one can never be sure. A marginal battery might cause PRAM corruption, so dead battery is better than a dying one. However, if she keeps her computer plugged in, there should be no issues. It is most certainly not worth a 200 mile trip.
