My TiBook is about 3 years old, 400MHz and I love it. Right after I did the 10.8.2 update my problems started. I had problems with the battery icon, so I did the re-issued 10.8.2 and that seemed to help. Just the other day I did the QuickTime & iTune updates and POW! my book does not see my battery anymore. It runs great with the power supply, but no battery. I get 3 out of 4 lights on the battery, it has a charge, but the book doesn't see it. I installed 10.3 thinking it was a software problem, but NO! Still does not see the battery. Any suggestions?
