Adding or Removing a Memory Module
Ä
CAUTION: The memory module sockets have gold-plated metal contacts.
When upgrading the memory, it is important to use memory modules with
gold-plated metal contacts to prevent corrosion and/or oxidation resulting
from having incompatible metals in contact with each other.
Ä
CAUTION: Static electricity can damage the electronic components of
the computer. Before beginning these procedures, ensure that you are
discharged of static electricity by briefly touching a grounded metal
object. See Appendix D, “Electrostatic Discharge” for more information.
Ä
CAUTION: When handling a memory module, be careful not to touch
any of the contacts. Doing so may damage the module.
