(a) ObjectSupportLib and (b) Resetting the Power Manager a. We have previously covered the confusion over all the different versions of ObjectSupportLib that exist. Apple now has an official explanation in a new Technote 1095.
b. How to reset the Power Manager on each of the different PowerBook models is another frequent source of confusion. I had covered this issue in a now-deleted MacFixIt Reports item (it is now included in the third edition of Sad Macs). Apple explains it in a new TIL file (#0014449) and April 4 Information Alley article.
