Memory Module

Removing the Memory Module/Modem Cover

NOTE: This procedure covers removing and replacing the memory module located under the memory module/modem cover on the bottom of the computer. A second memory module resides on the upper surface of the system board under the EMI shield. To replace the memory module under the EMI shield, perform the procedure for removing the EMI shield. Then replace the memory module.

NOTICE: Disconnect the computer and any attached devices from electrical outlets, and remove any installed batteries.

NOTICE: To avoid ESD, ground yourself by using a wrist grounding strap or by touching an unpainted metal surface on the computer.

NOTICE: Read "Preparing to Work Inside the Computer" before performing the following procedure.

1. Turn the computer over, and remove the memory module/modem cover:
   
   
   1. Remove the M2.5 x 5-mm screw from the memory module/modem cover.
      
      
   2. Slide the cover out approximately 10 mm, and lift it away from the computer.

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

2. 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.
   
   

The module should pop up.

3. 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 hear a click. If you do not hear the click, remove the module and reinstall it.
      
      

4. Replace the cover and screw:
   
   
   1. Place the memory module/modem cover over the memory module/modem compartment so that the end of the cover with the screw hole is lined up with the lines and arrows on the bottom of the computer.
      
      
   2. Press down on the center of the memory module/modem cover, and slide the cover until it is secured.
      
      
   3. Replace and tighten the M2.5 x 5-mm screw.
      
      

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