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 49 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 as 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 require 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 toward the
center of the module.
1 Remove the side panel.
2 Locate the DDR2 DIMM socket on the mainboard.
