bay. Then press down and in on the drive door until it snaps into position, flush with the computer case.

5. Replace the screws you removed in step 2. Be careful not to overtighten the screws.

If you have installed a new hard-disk drive, follow the directions that came with the drive to partition and logically format the drive and to create an

S2D partition.

Preparing a New Primary Drive

Every primary hard-disk drive must be physically formatted, partitioned, and logically formatted before it can be used to store data. Every primary

hard-disk drive from Dell is physically formatted before it is sent to you. Use the program(s) provided by your operating system to partition and

logically format the hard-disk drive. For more information, see both your operating system and your drive documentation.

Installing Memory Modules

Your system's factory-installed memory can range from 64 megabytes (MB) to a system maximum of 320 MB. Depending on the memory already

installed, you may be able to increase memory by installing a 32-, 64-, or 128-MB synchronous dynamic random-access memory (SDRAM) small-

outline dual-inline memory modules (SODIMMs) in the memory upgrade socket. The maximum achievable memory for your system depends on the

system's original memory configuration.

NOTICE: Dell Latitude CS/CSx portable computers support only SDRAM SODIMMs. Extended-data out (EDO) memory modules are

notsupported.

To upgrade computer memory, you can install or replace a memory module through the memory module cover on the underside of the

computer.To prepare the computer for the removal or installation of a memory module, perform the following steps.

NOTICE: Ground yourself by touching an unpainted metal surface of a connector on the back of the computer. While you work,

periodically touch the connector to dissipate any static electricity that might harm internal components.

1. Turn off the computer and any attached devices.

Do not install memory modules while the computer is in suspend, standby, or suspend-to-disk mode.

2. If the computer is docked, undock it.



3. Disconnect the computer and peripherals from their electrical outlets to reduce the potential for personal injury or shock.



4. Disconnect any telephone or telecommunication lines from the computer.

To remove or install a memory module, perform the following steps.

NOTICE: To avoid scratching the top of the computer, make sure that your work surface is clean. You may want to put down a

protective mat before turning over the computer.

1. Close the display, turn the computer upside down, and remove the memory module cover (see Figure 2).

Use a #1 Phillips-head screwdriver to remove the two screws securing the memory module cover. When the memory module cover pops up

slightly, lift it up and remove it to expose the memory socket or installed memory module beneath.

2. If you are replacing a memory module, remove the old one.

Carefully spread apart the inner metal tabs of the memory module socket just far enough for the memory module to disengage from the

socket (it should pop up slightly). Then lift the memory module away from the socket (see Figure 3).
