About the Computer’s Battery
The Macintosh has a 3.6 V lithium backup battery installed on the main logic board. Some
signs that you need to replace the battery are intermittent problems starting up your
computer and the date randomly resetting. Replacement batteries for the Macintosh are
available in many electronics and computer stores. You can install the new battery yourself or
have an Apple-authorized dealer do it for you for a fee.
Replacing the battery may cause some settings on your computer, such as the date and
network settings, to revert to factory default settings. You may also have to restore modem
settings in any communications programs you are using.
Warning To avoid damaging your computer and expansion card, do not attempt to
install any expansion card without first checking the documentation for that card. If the
documentation specifies that an Apple-certified technician must install the card (usually
because the installation requires special training or tools), consult the service and support
information that came with your computer for instructions on how to contact an Apple-
authorized service provider for assistance. If you attempt to install the card yourself, any
damage you may cause to the computer or card will not be covered by the limited
warranty on your computer. If the card is from a manufacturer other than Apple, check
with an Apple-authorized dealer or service provider to see if you can install it yourself.
Important Make a note of the settings for communications programs before you replace
the battery.
