Memory Upgrade
Module
Your Fujitsu LifeBook T4200 Series Tablet PC comes with
a minimum of 512 MB of high speed Double Data Rate 2
Synchronous Dynamic RAM (DDR2 SDRAM), 667 MHz
factory installed. The maximum memory capacity is 4 GB
(2 GB x 2), but 3.25 GB is the maximum amount that is
usable by the operating system. To increase your system’s
memory capacity, you may install an additional memory
upgrade module. The memory upgrade must be a dual-
in-line (DIMM) SDRAM module. To ensure 100%
compatibility, purchase the SDRAM module only from
the Fujitsu web store at us.fujitsu.com/computers
.
INSTALLING MEMORY UPGRADE MODULES
1. Turn off power to your LifeBook Tablet PC and
remove any power adapter (AC or auto/airline).
2. Make sure that all the connector covers are closed.
3. Turn the Tablet PC bottom side up, and remove the
screws of the memory upgrade module compart-
ment.

■ 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.
■ The memory upgrade module can be
severely damaged by electrostatic dis-
charge (ESD). To minimize risk to the
module, observe the following precau-
tions:
■ Before handling a memory module,
touch a grounded metal object to
discharge static electricity built up in
your body.
■
When installing or removing a
memory module, hold it by the edge
so as not to touch any contacts or
chips. Be careful not to touch any
internal computer terminals or
components; the oil from your
fingers could cause a short to the
components.
■ Be sure to power down your system
before adding or removing memory
modules. Even if the system is in
hibernate or standby states, data
could be lost or the memory could be
damaged if power is still available to
the system.
