CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface.
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.
CAUTION: To help prevent damage to the system board, remove the main battery (see Removing the Battery) before working inside the computer.
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:
One full Mini-Card slot - for Mobile Broadband or Wireless Wide Area Network (WWAN)
One half Mini-Card slot - for Wireless Local Area Network (WLAN)
NOTE: Depending on the configuration of the computer when it was sold, the Mini-Card slots may or may not have Mini-Cards installed in them.
Release the Mini-Card by removing the two screws that secure the
Mini-Card to the system board connector.
Lift the Mini-Card out of its system board connector.
CAUTION: When the Mini-Card is not in the computer, store it in protective antistatic packaging (see "Protecting Against Electrostatic Discharge" in the safety instructions that shipped with your computer).
Replacing the Mini-Card
Remove the new Mini-Card from its packing.
CAUTION: Use firm and even pressure to slide the card into place. If you use excessive force, you may damage the connector.
CAUTION: The connectors are keyed to ensure correct insertion. If you feel resistance, check the connectors on the card and on the system board, and realign the card.
CAUTION: To avoid damage to the Mini-Card, never place cables under the card.
Insert the Mini-Card at a 45-degree angle into the appropriate system
board connector. For example, the WLAN card connector is labeled
WLAN and so on.
Press the other end of the WLAN card down into the slot on the system
board and replace the two screws that secure the card to the system board
connector.
Connect the appropriate antenna cables to the Mini-Card you are
installing. The following table provides the antenna cable color scheme for
