computer.  
You can increase your computer memory by installing memory modules on the system board. See "Specifications" in your Setup Guide for information on the  
type of memory supported by your computer. Install only memory modules that are compatible with your computer.  
NOTE: Memory modules purchased from Dell are covered under your computer warranty.  
Your computer has two user-accessible SODIMM sockets that can be accessed from the bottom of the computer.  
Removing the Memory Module(s)  
1. Follow the procedures in Before You Begin.  
2. Remove the battery (see Removing the Battery).  
3. Remove the base cover (see Removing the Base Cover).  
CAUTION: To prevent damage to the memory module connector, do not use tools to spread the memory module securing clips.

CAUTION: Only a certified service technician should perform repairs on your computer. Damage due to servicing that is not authorized by Dell™  
is not covered by your warranty.  
NOTE: Dell does not guarantee compatibility or provide support for Mini-Cards from sources other than Dell.  
If you ordered a wireless Mini-Card with your computer, the card is already installed.  
Your computer supports two Mini-Card slots:  
l
l
one full Mini-Card slot for WWAN  
one half Mini-Card slot for WLAN  
The types of Mini-Cards supported are:  
l
l
Wireless Local Area Network (WLAN) Half Mini-Card  
Mobile broadband or Wireless Wide Area Network (WWAN) Full Mini-Card  
NOTE: Your computer can only support one full Mini-Card and one half Mini-Card at a time.  
NOTE: The WLAN slot supports a half Mini-Card.  
NOTE: Depending on the configuration of the computer when it was sold, one or more of the Mini-Card slots may not have Mini-Cards installed in them.  
Removing the Mini-Card  
1. Follow the instructions in Before You Begin.  
2. Remove the base cover (see Removing the Base Cover).  
CAUTION: When you disconnect a cable, pull on its connector or on its pull-tab, not on the cable itself. Some cables have connectors with locking  
tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep  
them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented  
and aligned.  
3. Disconnect the antenna cables from the Mini-Card.
