I definitely see it on a Dell laptop. I'm not aware of it happening on
my TiBook first-gen, but I'd expect it to.
The point is AFAICT that the battery will self-dicharge at a more or
less slow rate, and this charge loss will be compensated by regularly
recharging the battery a bit.
In general, this is considered good practice and doesn't adversly affect
battery life.
