Installing Additional Memory
Your computer comes with two memory slots, one above the other, that you access by
removing your PowerBook keyboard. Your computer comes with a 128 megabyte (MB)
Synchronous Dynamic Random-Access Memory (SDRAM) module installed in the lower slot.
The upper memory slot can accept a SDRAM module that meets the following specifications:
m Small Outline-Dual Inline Memory Module (SO-DIMM) format
m 1.25 inch or smaller
m 64, 128, 256, or 512 MB
m 144-pin
m PC-133 Type RAM
SDRAM from an earlier PowerBook that meets these specifications can be used with
your PowerBook.
The maximum amount of RAM you can install in your PowerBook is 1 GB, using 512 MB
DIMMs in both the upper and lower RAM slots.
Warning Apple recommends that you have an Apple-certified technician install memory
or remove the internal hard disk. Consult the service and support information that came
with your computer for instructions on how to contact Apple for service. If you attempt
any of these procedures and damage your equipment, such damage is not covered by the
limited warranty on your computer.
