Removing a Memory Module

1. Press out the securing clip at each end of the memory module connector.

2. Align the notch on the bottom of the module with the crossbar in the connector.
   
   

NOTICE: To avoid damage to the memory module, press the module straight down into the socket with equal force applied at each end of the module.

3. Insert the module straight down into the connector, ensuring that it fits into the vertical guides at each end of the connector. Press firmly on the ends of the module until it snaps into place.
   
   

If you insert the module correctly, the securing clips snap into the cutouts at each end of the module.

4. Close the computer cover.

NOTICE: To connect a network cable, first plug the cable into the network wall jack, and then plug it into the computer.

6. Connect your computer and devices to electrical outlets, and turn them on.
   
   

After you open and close the cover, the chassis intrusion detector, if enabled, causes the following message to appear on the screen at the next computer start-up:

ALERT! Cover was previously removed.

7. You must reset the chassis intrusion detector.
   
   

The computer detects that the new memory does not match the existing configuration information and generates the following message:

The amount of system memory has changed.
Strike the F1 key to continue, F2 to run the setup utility.

8. Press <F2> to enter system setup and check the value for System Memory.
   
   

The computer should have changed the value of System Memory to reflect the newly installed memory. Verify the new total. If it is correct, skip to step 10.

9. If the memory total is incorrect, turn off and disconnect your computer and devices from their electrical outlets. Open the computer cover and check the installed memory modules to ensure that they are seated properly in their sockets. Then repeat steps 4, 5, and 6.
   
   
10. When the System Memory total is correct, press <Esc> to exit system setup.
    
    
11. Run the Dell Diagnostics to verify that the memory modules are operating properly.
