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.

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