This chapter provides information and instructions for installing additional memory
and for removing and replacing the battery in your MacBook.
Your computer has two memory slots that you access by removing the computer’s
battery. Your MacBook comes with a minimum of 1 gigabyte (GB) of 667 MHz Double
Data Rate (DDR2) Synchronous Dynamic Random-Access Memory (SDRAM) installed.
Both memory slots can accept an SDRAM module that meets the following
specifications:
 Double Data Rate Small Outline Dual Inline Memory Module (DDR2 SO-DIMM) format
 1.25 inch or smaller
 512 MB or 1 GB
 200-pin
 PC2-5300 DDR2 667 MHz Type RAM
For best performance, fill both memory slots and install an identical memory module in
each slot.
WARNING: Apple recommends that you have an Apple-certified technician install
memory. Consult the service and support information that came with your computer
for information about how to contact Apple for service. If you attempt to install
memory and damage your equipment, such damage is not covered by the limited
warranty on your computer.
