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.
