Memory Upgrade Module
Your notebook has been configured with 256 MB, 512
MB, or 1 GB of high speed Synchronous Dynamic RAM
(SDRAM) factory installed. If you have 256 MB or 512
MB of memory installed, you can increase your note-
book’s memory capacity by replacing the original module
with a higher capacity module. The memory upgrade
must be a dual-in-line (DIMM) 100 MHz SDRAM
module. (To be certain the correct module is used, you
should only use Fujitsu memory modules. To order, go to
the Fujitsu Web site: http://us.fujitsu.com/computers).
REMOVING A MEMORY UPGRADE MODULE

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 battery
toward you.
