Memory Upgrade
Module
Your LifeBook notebook has been configured with
128MB of high speed Synchronous Dynamic RAM
(SDRAM) factory installed. To increase your notebook’s
memory capacity, you must replace the original memory
module with a higher capacity module. The memory
upgrade must be a dual-in-line (DIMM) 100 MHz
SDRAM module.

1. Turn off power to your notebook using the power
switch, and remove any attached power adapter
(AC or auto/airline).
2. Make sure that all connector covers are closed.
3. Turn the notebook bottom side up, with the front
panel toward you.
4. Remove the screws of the memory upgrade module
compartment. (Figure 4-6)

Press the connector edge of the module firmly down
