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 39 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 four 240-pin sockets on the mainboard support Double Data Rate 2 
(DDR2) 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 4 GB. 
The DDR2 DIMMs should work under 1.8 volts. You can install PC2-3200/
DDR2-400, or PC2-4300/DDR2-533 modules in the DDR2 DIMM sockets. 
Contact your dealer for qualified DIMM vendors. 
Each DDR2 DIMM socket is independent from the other. This independence 
allows you to install DDR2 DIMMs with different capacities to form different 
configurations.
To remove a DDR2 DIMM
Note: The DDR2 DIMM has only one notch located on the center 
of the module.
1
Remove the side panel (see page 44).

Locate the DDR2 DIMM socket on the mainboard.
