Memory Module

CAUTION: Before working inside your Dell™ computer, read the safety instructions in your System Information Guide.

CAUTION: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface.

NOTE: Memory modules purchased from Dell are covered under your computer warranty.

1. Follow the instructions in "Preparing to Work Inside the Computer."
   
   
2. Turn the computer over, loosen the captive screw from the memory module cover, and lift the cover.

NOTICE: To prevent damage to the memory module connector, do not use tools to spread the inner metal tabs that secure the memory module.

3. If you are replacing a memory module, remove the existing module.
   
   

NOTICE: Handle memory modules by their edges, and do not touch the components on a module.

1. Use your fingertips to carefully spread apart the securing clips on each end of the memory module connector until the module pops up.
   
   
2. Remove the module from the connector.

NOTICE: If you need to install memory modules in two connectors, install a memory module in the connector labeled "DIMMA (Slot 1)" before you install a module in the connector labeled "DIMMB."

4. Ground yourself and install the new memory module:
   
   
   1. Align the notch in the module with the slot in the center of the connector.
      
      
   2. Slide the edge of the module firmly into the connector, and rotate the module down until you feel a click. If you do not feel the click, remove the module and reinstall it.
      
      

NOTE: If the memory module is not installed properly, the computer does not boot. The Num Lock and Scroll Lock lights blink about ten times.

5. Replace the cover and screw.
   
   

NOTICE: If the memory module cover is difficult to close, remove the module and reinstall it. Forcing the cover to close may damage your computer.

6. Insert the battery into the battery bay, or connect the AC adapter to your computer and an electrical outlet.
   
   
7. Turn on the computer.
   
   

As the computer boots, it detects the additional memory and automatically updates the system configuration information.

Mini PCI Card

If you ordered a Mini PCI card at the same time that you ordered your computer, Dell has already installed the card for you.

CAUTION: Before working inside your computer, read the safety instructions in your System Information Guide.

CAUTION: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface.

NOTICE: Handle components and cards by their edges, and avoid touching pins and contacts.

1. Follow the instructions in "Preparing to Work Inside the Computer."
   
   
2. Turn the computer over, and loosen the captive screw on the Mini PCI card/modem cover.

Modules

Your computer ships with an optical drive installed in the module bay. However, the device screw is not installed in the optical drive but packaged separately. When you install your device in the module bay, you can install the device screw.

NOTE: You do not need to install the device screw unless you want to secure the module inside the computer for security purposes.

If the Device Screw Is Not Installed

NOTICE: To prevent damage to devices, place them in a safe, dry place when they are not installed in the computer. Avoid pressing down on them or placing heavy objects on top of them.

1. Press the device latch release so that the latch release pops out.
