CAUTION:
Your memory module sockets have gold metal contacts.
When upgrading your memory, it is important to use memory modules
with gold metal contacts to prevent corrosion and/or oxidation resulting
from having incompatible metals in contact with each other.

CAUTION:
Static electricity can damage the electronic components of
the computer or optional cards. Before beginning these procedures,
ensure that you are discharged of static electricity by briefly touching a
grounded metal object. See Appendix E, “Electrostatic Discharge,” for
more information.

CAUTION:
When handling a memory module, be careful not to touch
any of the contacts. Doing so may damage the module.
