Before you go out and plunk down $100 (or more) for a new battery, here are a few things you can try. (1) Reset the power manager. How you do this depends on the model of your Powerbook. Google on some combination of powerbook, battery and power manager to find out for your model. (2) Reset the PRAM and NVRAM on your machine. To reset the PRAM on most machines, hold down the option+apple+P+R at startup and let it bong three or four times to make sure you get the NVRAM and the PRAM. (3) You can also reset all this stuff by booting into the firmware and typing the commands reset-nvram and reset-all. You get into open firmware by pressing apple+option+O+F while booting. | The next meeting of the Louisville Computer Society will | be July 22.
