Removing and Installing Memory Modules
Memory modules for your computer are available in 32-, 64-, 128-, 192-, and 256-MB sizes.
To install memory module(s), perform the following steps.
NOTICE: Do not install or remove a memory module when the computer is turned on or in save-to-disk suspend mode.
1. Save and close any open files, exit any open application programs, and shut down the computer.
2. Unplug the computer and any attached peripherals from the electrical outlets.
3. Remove any installed batteries from the MegaBay and/or media bay. For instructions, refer to “ Storage Devices ."
4. Ground yourself by touching a metal input/output (I/O) connector on the back of the computer.
5. Turn the computer over, and remove the memory module cover as shown in Figure 1.
Slide the memory module cover as far as it will go in the direction of the arrow, and then lift it away from the computer.

NOTICE: To prevent damage to the computer, do not use tools to spread the inner metal tabs of the socket when you are installing or
removing a memory module.
6. If you are replacing one or more memory modules, remove the memory module(s) as shown in Figure 2.
Using your fingernails, carefully spread apart the inner metal tabs of the memory module socket just far enough for the memory module
to disengage from the socket (the module should pop up slightly). Then lift the memory module away from the socket.

*Not all valid memory configurations are available at all times. Contact Dell for details.
NOTE: Your computer has two memory module sockets (slot 1 and slot 2). You can install all sizes of memory modules you purchase
from Dell (but which Dell does not install), except the 192-MB memory module, in either socket. If you purchase a non-Dell-installed
192-MB memory module, you must install it in slot 2.
CAUTION: Before working inside your computer, read the “ Precautionary Measures ” section of this guide.

NOTE: If one memory module is already installed and you are adding a second memory module, put the second module in the
available slot. Removing existing module(s) is necessary only if they are being replaced. Depending on the configuration of your
computer, one or two modules may already be installed.
