I was so convinced that the part for my Powerbook was not going to fix the problem that I had written the machine off. The inverter arrived from Atlanta, however, and right now the old road warrior is working, at least in the naked, upside-down configuration.
It has worked for short spells in the past week though, so we won’t really know if things are fixed for a while yet. Cross your fingers!
Then I just have to figure out who to talk to over at Apple concerning their definition of “global”.
