Michael,
With all due respect, you are wrong. A bad PRAM battery will cause problems
on a machine that is fully plugged in. They are often subtle and non-repeatable
(hence my procedure to diagnose involving over 48 hours), but they do happen.
In the past I have fixed problems this way, so I know that this is the case.
You may not have seen this, but that does not change things.
