User Installable Features Memory Upgrade Module Your LifeBook notebook can be upgraded to include up to 2 GB of in-slot high speed Double Data Rate (DDR2) Synchronous Dynamic RAM (SDRAM). To increase your LifeBook notebook's memory capacity, you may install a larger memory upgrade module. Your LifeBook notebook has one SO-DIMM slot. The memory module is accessible via the memory compartment on the bottom of the system. If you install a memory upgrade module, it must be a SO-DIMM DDR2-667 SDRAM module. To ensure 100% compatibility, purchase the memory module only from the Fujitsu web store at us.fujitsu.com/computers. ■ 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 discharge (ESD). To minimize the risk, observe the following precautions: ■ 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. ACCESSING THE MEMORY COMPARTMENT To gain access to the memory compartment, follow these steps: You must turn off power and remove any modem connection before installing the memory upgrade module. 2. Place your LifeBook notebook with the bottom facing up on a clean work surface. 3. Remove the two screws from the holes in the memory compartment cover. (Figure 4-9) Figure 4-9. Removing memory compartment cover To increase the amount of memory, remove the smaller module from the DIMM slot and replace with a larger one. REMOVING A MEMORY MODULE 1. Perform steps 1 through 3 of Accessing the Memory Compartment. 2. Pull the module clips sideways away from each side of the memory module simultaneously. (Figure 410) Module Clips Figure 4-10. Removing a memory module 3. While holding the clips out, remove the module from the slot by lifting it up and pulling towards the back of your LifeBook notebook. 4. Store the memory upgrade module in a static guarded sleeve. 5. Install a new memory module as detailed in the procedure below. 6. Replace the memory compartment cover. (Figure 412) 1.
