Notes on adding/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.
❑ There are two memory module slots in the memory module compartment. If your computer has only one memory module
installed at the time of delivery, it has been inserted in the upper slot. To insert a new memory module into the lower open
slot for increasing the amount of memory, remove the memory module from the upper slot first, and then insert the new
memory module into the lower slot and reinsert the removed memory module.
❑ 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 source (that is, battery pack or AC adapter) and from any
telecommunication links, networks, or modems 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.
❑ Do not open the memory module package before you are ready to change the module. The package protects the
module from ESD.
