Upgrading the System Memory
Many applications will generally run faster when the computer’s dynamic memory capacity is increased. The computer provides two DDR2 memory sockets. There is one located underneath the System Device Cover andanother one located underneath the keyboard. You can increase the amount of memory by replacing the existing one with a dual inline memory module (commonly known as SO-DIMM) of a higher capacity. The SO-DIMM can be 256MB, 512MB, or 1024MB in capacity. The SO-DIMM is of type DDR2 SDRAM, has 200 pins and runs on 1.8V.

Warning: Memory upgrade is a delicate process. Please observe the followinginstructions carefully or have a qualified technician install it for you. Damages due to mishandling of this procedure are NOT covered by the manufacture’s warranty.
