Replace the Computer’s Backup Battery
If you have intermittent problems starting up your computer and the date is reset to
something other than the current year, you need to replace the backup battery in your
computer.
For some computers, you can replace the battery yourself. For others, you must have an
Apple-authorized service provider do this for you. To find out if your computer’s battery is
user-replaceable, see the documentation that came with your computer.
Replacing the battery may affect the settings in some of your control panels, including the
following:
m Date & Time
m Memory (information lost includes RAM disk settings)
m Monitors & Sound
m Keyboard and Mouse (or Trackpad)
m AppleTalk (“Connect via” is set to the Ethernet port)
m Map
Make a note of the settings before you replace the battery. You may also have to restore
modem settings in any communications software programs you are using.
Important Batteries contain chemicals, some of which may be harmful to the environment.
Please dispose of used batteries according to your local environmental guidelines.
