NOTE: Dell does not guarantee compatibility or provide support for Mini-Cards from sources other than Dell.
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.
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.
