Doug - this is exactly the way of resetting the current MacBookPro, but I had not realised that it was an option as far back as the Ti-book.
This is the first I heard of it in relation to a Ti-book.

This procedure is currently used to reset the SMC (System Management Controller).

I was pleased to see that it fixed your problem.

We should all use this as part of our trouble-shooting procedure......
