Adding Memory

You can increase your computer memory by installing a memory module on the system board. See the "Specifications" section in your System Information Guide for information on the memory supported by your computer. Be sure to add only a memory module that is intended for your computer.

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

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the System Information Guide.

1. Ensure that the work surface is flat and clean to prevent scratching the computer cover.
   
   
2. Save and close any open files, exit any open programs, and shut down the computer.
   
   
3. If the computer is connected to the media base (docked), undock it. See the documentation that came with your media base for instructions.
   
   
4. Disconnect the computer from the electrical outlet.
   
   
5. Wait 10 to 20 seconds, and then disconnect any attached devices.
   
   
6. Remove any installed PC Cards and battery.
   
   

NOTICE: Handle components and cards by their edges, and avoid touching pins and contacts. Ground yourself by touching a metal connector on the back of the computer. Continue to ground yourself periodically during this procedure.

7. Turn the computer over, unscrew both captive screw(s) from the memory module/Mini PCI/modem cover, and remove the cover.

2	memory module cover	H0164

NOTICE: To prevent damage to the memory module connector, do not use tools to spread the memory module securing clips.

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

NOTICE: Handle components and cards by their edges, and avoid touching pins and contacts. Ground yourself by touching a metal connector on the back of the computer. Continue to ground yourself periodically during this procedure.

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.

9. Ground yourself and install the new memory module:
   
   
   1. Align the notch in the module edge connector with the tab in the center of the connector slot.
      
      
   2. Slide the module firmly into the slot at a 45-degree angle, and rotate the module down until it clicks into place. If you do not hear the click, remove the module and reinstall it.
      
      

NOTE: If the memory module is not installed properly, the computer may not boot properly. No error message indicates this failure.

10. Replace the cover.
    
    

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

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

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

To confirm the amount of memory installed in the computer:

• In the Microsoft® Windows® XP operating system, click the Start button, click Help and Support, and then click Computer Information.
  
  
• In Windows 2000, right-click the My Computer icon on your desktop, and then click the General tab.
