Upgrading your computer
Certain components of your computer are upgradeable such as the
memory, the hard disk, the CPU and the expansion cards. You need to
observe the “Installation precautions” on page 47 when installing or
removing a computer component. However, for safety purposes, we
do not recommend that you perform these upgrades yourself. If you
want to replace or upgrade any of these components, contact your
dealer or a qualified service technician for assistance.
Note: The mainboard model shown in the following figures may
not be exactly the same with the one found in your computer.
Installing additional memory
The two 184-pin sockets on the mainboard support Double Data Rate
(DDR) Synchronous Dynamic Random Access Memory (SDRAM)-type
DIMMs. You may install 128-MB, 256-MB, 512-MB or 1-GB DIMMs for a
maximum memory capacity of 2 GB.
Note: To capitalize on the system memory capacity mentioned
above, you must use 1-GB memory modules which are not yet
available in the market. The biggest capacity currently available is
512-MB which allows a maximum of 1GB.
The DDR DIMMs should work under 2.5 volts. You can install PC2100/
DDR266 DDR modules in the DDR DIMM sockets. Contact your dealer
for qualified DIMM vendors.
Each DDR DIMM socket is independent from the other. This
independence allows you to install DDR DIMMs with different
capacities to form different configurations.
To remove a DDR DIMM
Note: The DDR DIMM has only one notch located on the center
of the module.
1 Remove the side panel (see page 49).
