Adding and Removing Memory

If you want to expand the functionality of your computer, you can increase the amount of memory by replacing the installed 
memory module. Before you upgrade your computer's memory, read the notes and procedures in the following pages.

Notes on adding memory modules

❑ Be sure to place your computer on a flat surface before adding or removing memory modules.
❑ Be careful when changing memory. Improper installation of memory modules may cause damage to your system. This 

damage may void your manufacturer's warranty.

❑ Only use memory modules that are compatible with your computer. If a memory module is not detected by the computer 

or the Windows operating system becomes unstable, contact the sales dealer or the manufacturer of your memory 
module.

❑ Electrostatic discharge (ESD) can damage electronic components. Before touching a memory module, ensure the 

following:
❑ The procedures described in this document assume user familiarity with the general terminology associated with 

personal computers and with the safety practice and regulatory compliance requirements for using and modifying 
electronic equipment.

❑ Turn off your computer and disconnect it from its power sources (battery pack and AC adapter) and from any 

telecommunication links or networks before you remove any cover or panel from the computer. Failure to do so may 
result in personal injury or equipment damage.

❑ ESD can damage memory modules and other components. Install the memory module only at an ESD workstation. 

If such a station is not available, do not work in a carpeted area, and do not handle materials that produce or hold 
static electricity (cellophane wrappers, for example). Ground yourself by maintaining contact with an unpainted metal 
portion of the chassis while performing the procedure.
