Electrostatic Discharge (ESD)
Static electricity, a normal and natural phenomenon, builds up on your body
as you walk around. You experience an electrostatic discharge (ESD) when
you touch an object and feel a spark. ESD can cause damage to the
internal components of your computer.
To avoid ESD damage, read and follow all instructions. If a grounding wrist
strap is included with your replacement memory, refer to the instructions
included for how to ground and use the strap.
About Memory
Your computer comes with a minimum of 64 megabytes (MB) of
synchronous dynamic random-access memory (SDRAM) installed in a
RAM slot on the bottom of the processor module. On the top of the
processor module is another RAM slot you can use to add additional
memory to your PowerBook.
RAM Specifications
The expansion slots on the top and bottom of the processor module can
accept up to a 2-inch SDRAM card that meets the following specifications:
• small outline-dual inline memory module (SO-DIMM) format
• 16, 32, 64, 128, or 256 MB
• 144-pin
• PC-100 Type RAM
SDRAM from earlier PowerBook models cannot be used.
Maximum RAM Configurations
The maximum amount of RAM you can install in your PowerBook is 512
MB, using 256 MB DIMMs in both the top and bottom RAM slots. To install
RAM in the bottom RAM slot, refer to the document called “Memory (RAM)
Replacement Instructions.”
