chassis. I have both types of MAC. It could have just been a coincidence,
but replacing the battery allowed me to get the disk to eject for the first
time. The AA battery is installed like any toy with batteries...there's a
little plastic flap/cover you pop off on the outside of the case. I am
sure that there is a web resource that explains the battery, I did not look
very hard. I will be demoing the Mac in class later in the semester and I
will by then do more research.
