Another 15″ PowerBook Battery Update

In case the last one didn’t extend the battery life on your 15″ PowerBook, maybe this one will.  The update should be in your Software Update, but if you want to check manually to see if you’re a lucky winner, Apple’s provided a page to help. 

Basically, Go to the Apple Menu, and click, “About This Mac”. 
Then choose “More Info”.

Check the Machine Model, and match it against the table below.
