CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by
periodically touching an unpainted metal surface, such as a connector on the back of the computer.
If you ordered a WLAN card with your computer, the card is already installed.
NOTICE: To prevent damage to the connector, do not use tools to release the securing tabs.
If a WLAN card is not already installed, go to step 5. If you are replacing a WLAN card, remove the
existing card:
Disconnect the antenna cables from the card.
NOTE: The WLAN card may have two or three antenna connectors, depending on the type of card you have.
Release the card by pushing the metal securing tabs away from the card until the card pops up
slightly.
Slide the card at a 45-degree angle out of its connector.
NOTICE: The card connector is keyed to ensure correct insertion. If you feel resistance, check the connector and
realign the card.
NOTICE: Do not insert a Mobile Broadband network (WWAN) card into the WLAN card connector.

CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically
touching an unpainted metal surface, such as a connector on the back of the computer.
NOTICE: Do not touch the SIM card connectors to protect the card from electrostatic discharge (ESD). To prevent
ESD, hold the card in your hand before you insert or remove the card.
Turn the computer over.
With the cut-off corner on the card facing away from the card compartment, insert the SIM card into
the compartment (as shown) so that it slides under the metal bracket on the sides.
Ground yourself by touching one of the metal connectors on the back of the computer.
NOTE: If you leave the area, ground yourself again when you return to the computer.
Slide the antenna cables out of the protective sleeve and away from the top of the FCM card.
Release the card by pushing the metal securing brackets away from the card until the card pops up

FCM card
NOTICE: When installing this card, ensure the two antenna cables are not under the card. The antenna cables are
designed to lay across the top of the FCM card and into the protective sleeve. Installing the card on top of these
antenna cables may cause damage to your computer. Also, do not install the FCM card in the WLAN card
connector. The FCM card is designed to work in the WWAN card connector. Installing the card in the wrong slot
may cause damage to your computer.
Align the new FCM card with the connector at a 45 degree angle, and then press the card into the
connector until it clicks.
Reconnect the antenna cables to the top of the FCM card.
