Hey, gang I just got a Rev A Powerbook (TiBook). Everything on it works great, but I've been experiencing some problems with the battery. When it gets to around 82% or so, the computer shuts off / goes to permanent sleep until I plug the power cord back in. When I do so, it can be activated but the battery display says that it's at 0%. This has happened a few times now - every single time the battery drops to about the low 80s/high 70s. Has anyone experienced this? Is it a problem with the battery or the problem with my settings? I've downloaded coconut battery and it reads the battery strength exactly the same as the system itself does. I just don't want to run into a situation where I'm taking notes in class only to have my computer shut off until I can reach the nearest outlet. Thanks.
