Memory Upgrade
Module
Your LifeBook comes with 64MB or 128MB high speed
Synchronous Dynamic RAM (SDRAM) factory installed.
To increase your LifeBook’s memory capacity, you may
install an additional memory upgrade module. You can
also replace the original memory module with a higher
capacity module. The memory upgrade must be a dual-
in-line (DIMM) SDRAM module, however it can be any
capacity up to 512MB (total).
INSTALLING A MEMORY UPGRADE
MODULE
1. Turn off power to your LifeBook using the power
switch, and remove any power adapter
(AC or auto/airline).
2. Make sure that all the connector covers are closed.
3. Turn the LifeBook bottom side up, with the front
panel toward you.
4. Remove the screw at the front of the memory
upgrade module compartment. (Figure 4-10)
5. Remove the cover by tilting the front edge up
and then pulling forward until the tabs on the

6. Remove the memory upgrade module from the
static guarded sleeve.
7. Align the memory upgrade module with the part
side up. Align the connector edge of the memory
upgrade module with the connector slot in the
compartment. The connector will be pointing
toward the rear of the LifeBook.
8. Insert the memory upgrade module at a 45° angle.
Press the connector edge of the module firmly down
and into the connector until it lodges under the
retaining clip. You will hear a click when it is prop-
erly in place. (Figure 4-11)

CAUTION
Do not remove any screws from the memory upgrade
module compartment, except the ones specifically
shown in the directions for installing and removing
the memory upgrade module.
CAUTION
The memory upgrade module can be severely damaged
by electro-static discharge (ESD). Be sure you are
properly grounded when handling and installing the
module.
POINT
The memory upgrade module is not something you
routinely remove from your LifeBook. Once it is
installed, you can leave it in place unless you want
to increase system memory capacity.
