I’m glad to report that the battery charged to 100% yesterday and my Macbook is back in action, still minus the CD / DVD drive. Unfortunately, the DVD drive is packed away from owner’s prying hands. Its a Matshita DVD-R UJ-857. I wonder if there are instructions anywhere to replace it?

I’m not going to bother with this now, but its nice to know that its possible.
