Apple Portables: Calibrating your computer’s battery for best performance

1. Plug in the power adapter and fully charge your PowerBook’s battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
2. Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
3. Disconnect the power adapter while the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, the low battery warning dialog appears on the screen.
4. At this point, save your work.  Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep.
5. Turn off the computer or allow it to sleep for five hours or more.
6. Connect the power adapter and leave it connected until the battery is fully charged again.

You can use a higher wattage power adapter with an Apple portable computer, but you cannot use one with less wattage without potential operating issues.

A “kernel panic” is a low-level failure of the Mac OSX operating system. It seldom occurs. When it does, it suggests a corrupted system or a hardware failure that has caused a corrupted system. Not good.
