Memory Upgrade Module

Your notebook has two memory slots, and the system comes with 1 GB, 2 GB, or 4 GB of factory-installed memory. If you have a module installed in only one slot, you can increase your memory capacity by installing another memory module in the empty slot or by increasing the size of the single installed module. The minimum amount of memory in your system is 1 GB.

■Systems with Microsoft Windows Vista installed require a minimum of 512 MB of memory, but 1 GB or more is recom- mended.

■If 4 GB of memory is installed in your system, only 3.25 GB are usable, due to operating system constraints.

Your notebook supports dual-channel memory, which can have a significant effect upon your system’s perfor- mance. In order to support dual-channel memory, two DIMM modules must be installed in your computer.

■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:

■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. Do not to touch any internal computer terminals or components; the oil from your fingers could cause a short to the components.

■Power down your system before you add or remove 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.

The installation of incompatible memory modules can cause numerous problems which could result in loss of data. Memory upgrades must be PC2-5300 DDR2-667 SO-DIMM modules. Fujitsu highly recom- mends that you only purchase additional memory from the Fujitsu on-line accessory store at: us.fujitsu.com/computers.

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 notebook.

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 4-12)
