Ŷ chapter 4 upgrading your computer
Upgrading the System Memory
Many applications will generally run faster when the computer’s
dynamic memory capacity is increased. The computer provides two
DDR memory sockets, which are located underneath the system
device cover. 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 128MB, 256MB,
512MB, or higher in capacity. Depending on the model, your computer
may use DDR I SDRAM (2.5V) or DDR II SDRAM (1.8V).
Before the upgrade
: In order to find out what type of DDR module the
system uses, you need to reboot the system. The initial boot message
shows you what type of DDR SDRAM module your notebook uses.

Warning:
A memory upgrade is a delicate process. Please observe the following
instructions carefully or have a qualified technician install it for you. Damages due to
mishandling of this procedure are NOT covered by the manufacturer's warranty.
Warning:
Changing memory while your computer is in suspend or power-saving
mode may cause permanent damage to the hardware. Make sure you turn off the power
and unplug the AC cord before proceeding with a memory upgrade.
Warning:
You should only use the DIMM module that is approved by the reseller or
the manufacturer; otherwise the system may become unstable.
