The internal backup battery provides enough power to maintain the contents of RAM for up to 3 minutes while you change the battery. Note: If you have installed additional memory in your PowerBook, the backup battery may provide power for less than three minutes. Also, changing batteries several times in a short period can shorten the length of time the backup battery can maintain data if the backup battery hasn't had time to fully recharge. Important: If only one flashing light is on, very little charge is left. If no lights are visible, the battery is completely drained and the computer will not start up unless the power adapter is connected. Plug in the power adapter to let the battery recharge, or replace the drained battery with a fully charged battery (see page 53).

This saves battery life as charging is not continuously cycled on and off. 52 Chapter 3 Using Your Computer Removing and Replacing the Battery To remove the battery: m Shut down your PowerBook.
