Installing Memory and Replacing the Backup Battery

This section provides information about memory and the backup battery and explains how to

install them.

About Memory

Your computer contains two types of memory—dynamic random-access memory (DRAM) and

video memory. You can add DRAM to your computer in packages called Small Outline Dual

Inline Memory Modules, or SO-DIMMs.

The following illustration shows the locations of memory slots on the logic board. See the

sections that follow for important information about DRAM and video memory.

DRAM Configurations

Your computer comes with a 32 megabyte (MB) SO-DIMM pre-installed. You can increase your

computer’s DRAM up to 256 megabytes (MB) by adding SO-DIMMs to the two RAM DIMM

slots on the main logic board.

Warning Apple Computer recommends that you have an Apple-certiﬁed technician install

memory. Apple does not provide telephone support for memory upgrades. Consult the

service and support information that came with your computer for instructions on how to

contact an Apple-authorized service provider or Apple for service. If you install these items

yourself, you risk damaging your equipment, and this damage is not covered by the limited

warranty on your computer. See an Apple-authorized dealer or service provider for

additional information about this or any other warranty question.
