56 5 Upgrading your computer

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.
