•one half Mini-Card slot – for WLAN

The types of Mini-Cards supported are:

•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.
