Removing the Primary System Memory (RAM)
The computer has
three
memory sockets for 204 pin Small Outline Dual In-line (SO-DIMM)
DDR III (DDR3)
type memory
modules. The total memory size is automatically detected by the POST routine once you turn on your computer.
Note that
three SO-DIMMs are only supported by Quad-Core CPUs
;
Dual-Core CPUs support two SO-DIMMs maxi-
mum.
Two primary memory sockets are located under component bay cover (the bottom case cover), and one secondary
memory sockets are located under the keyboard (not user upgradable)
.
If you are installing only two RAM modules
then they should be installed in the primary memory sockets under the component bay cover.
Primary System Memory Upgrade Process
1.
Turn
off
the computer, turn it over and remove the battery (
page 2 - 5
) and remove the component bay cover
(
page 2 - 9
).
2.
The RAM modules will be visible at point
on the mainboard.
3.
Gently pull the two release latches (
&
) on the sides of the memory socket in the direction indicated by the
arrows (
Figure 10b
).
The RAM module
will pop-up
(
Figure 10c
)
, and you can then remove it
.
4.
Pull the latches to release the second module if necessary.

Module Removal
a. The RAM modules will
be visible at point
on the mainboard.
b. Pull the release lat-
ches.
c. Remove the module.
Contact Warning
Be careful not to touch
the metal pins on the
module’s connecting
edge. Even the cleanest
hands have oils which
can attract particles, and
degrade the module’s
performance.
