Memory Upgrade
Module
Your Fujitsu LifeBook comes with 64MB, 128MB, or
256MB high speed Synchronous Dynamic RAM
(SDRAM) factory installed. To increase your LifeBook’s
memory capacity, you can 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 up to 256MB capacity.
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 screws of the memory upgrade module
compartment. (Figure 4-12)
5. Remove the cover.

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 4-13)

The memory upgrade module can be severely damaged
by electro-static discharge (ESD). Be sure you are prop-
erly grounded when handling and installing the module.
P O I N T
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 change system memory capacity.
